Various types of ceramic crucibles: quartz, alumina, boron nitride, zirconia

As an important component of chemical instruments, crucibles are containers for melting and refining metal liquids, as well as solid-liquid heating and reaction. They are the basis for ensuring the smooth progress of chemical reactions. Historically, crucibles were originally made of clay, and one of the earliest uses of platinum was also for preparing crucibles. However, with the development of preparation technology, crucibles can now be made of any material that can melt or change its contents.

There are many types, models, and specifications of crucibles, which can be selected at will, with strong applicability, and can ensure the purity of the smelted material. Among them, ceramic crucibles are an important component of crucibles, and ceramic crucibles can be divided into quartz crucibles, corundum crucibles, boron nitride crucibles, zirconia crucibles, etc. according to the raw materials, and are used in different occasions according to their respective properties.

1. Quartz Ceramic Crucible

Quartz ceramic crucible, full name high-purity fused quartz ceramic crucible (silicon dioxide content ≥ 99.9%), is a ceramic crucible made of high-purity fused quartz as raw material. It has the characteristics of fine structure, low thermal conductivity, small thermal expansion coefficient, good thermal shock stability, good electrical properties, good chemical corrosion resistance, etc. Therefore, quartz ceramic crucible is widely used in the glass deep processing industry, metallurgical industry, electronics industry, chemical industry, aerospace, and other fields. Generally speaking, its shapes are mainly square and cylindrical.

With the attention and development of environmentally friendly energy, solar energy as a green energy has been widely valued by countries around the world. The use of polysilicon for solar energy conversion has increased dramatically, which has promoted the rapid development of polysilicon production. Therefore, the use of large-sized thin-walled square fused quartz ceramic crucibles has also increased dramatically, and the international market prospects are very optimistic about it.

2. Alumina crucible

Corundum crucible, scientific name alumina crucible, people usually call crucibles with an alumina content of more than 95% corundum crucibles. Corundum crucibles are hard and resistant to melting, high-temperature resistance, acid and alkali resistance, rapid cooling, and extreme heat resistance, chemical corrosion resistance, suitable for using anhydrous Na2CO3 and other weak alkaline substances as a flux to melt samples, but not suitable for using Na2O2, NaOH and other strong alkaline substances and acidic substances as a flux to melt samples.

99.70% corundum crucibles have good high-temperature insulation and mechanical strength in an oxidizing and reducing atmosphere of 1650℃-1700℃, and the short-term use temperature can reach up to 1800℃. According to the application conditions, alumina crucibles are available in a variety of sizes and shapes, such as arc crucibles, round bottom crucibles, straight crucibles, square crucibles, etc.

3. Boron nitride crucible

The common types of boron nitride are cubic boron nitride (C-BN) and hexagonal boron nitride (h-BN). Among them, boron nitride crucibles are usually made of h-BN. h-BN ceramics have good heat resistance, thermal stability, thermal conductivity, and high-temperature dielectric strength. They are ideal heat dissipation materials and high-temperature insulation materials.

Due to the excellent chemical stability of h-BN, it can resist the erosion of most molten metals. Because of the above-mentioned high-temperature insulation properties, high thermal conductivity, and low thermal expansion, it is most suitable as a material used in strict environmental conditions such as semiconductor processes. h-BN crucibles are often used for melting metals and semiconductors. Its operating temperature under vacuum is as high as 1800 degrees, and its operating temperature under atmosphere protection can reach up to 2100℃. It is generally protected by nitrogen or argon (atmosphere protection is to prevent the crucible from oxidation).

4. Zirconia crucible

The melting point of zirconia is higher than that of zirconium, reaching 2700℃. It is one of the materials with the best refractory performance in nature. Even if it is heated to 1900℃, it will not react with molten aluminum, iron, nickel, platinum, and other metals, silicates, and acidic slags. Therefore, Zirconia crucibles can successfully melt platinum, palladium, ruthenium, cesium, and other platinum group precious metals and their alloys.

It is worth noting that although zirconia is more expensive than alumina, it is a special oxide refractory material that cannot be replaced by other oxide materials when used in high-temperature furnaces above 2000℃.

Application and precautions of various ceramic crucibles

As an important part of chemical equipment, crucible is a container for melting and refining metal liquid and heating solid-liquid reaction, which is the basis for the smooth progress of chemical reaction. Crucibles were originally made of clay, and one of the earliest uses of platinum was to make crucibles. With the development of manufacturing technology, crucibles can now be composed of any material capable of melting or changing its contents.

There are many types, models and specifications of crucibles, which can be selected arbitrarily, with strong applicability and can ensure the purity of the molten material. Ceramic crucibles are an important part of crucibles. According to the raw materials, ceramic crucibles can be divided into quartz crucibles, corundum crucibles, boron nitride crucibles, zirconia crucibles, etc., and are used in different occasions according to their different properties.

Quartz ceramic crucible (silica content ≥ 99.9%)

Quartz ceramic crucible is a ceramic crucible made of high-purity fused quartz. It has the characteristics of fine structure, low thermal conductivity, small thermal expansion coefficient, good thermal shock stability, good electrical performance, and good chemical resistance. It is widely used in glass deep processing. Industry, metallurgical industry, electronics industry, chemical industry, aerospace and other fields. Generally speaking, the shapes of quartz ceramic crucibles are mainly square and cylindrical.

Corundum (Alumina) Crucible

Corundum crucible, the official name is alumina crucible, when the alumina content exceeds 95%, it is usually called corundum crucible. Corundum crucible is strong and resistant to melting, high temperature, acid and alkali, cold and extreme heat, and chemical corrosion. It is suitable for melting samples of weakly alkaline substances such as Na2CO3 without water, but it is not suitable for melting samples with water. Alumina crucibles are available in a variety of sizes and shapes depending on the application conditions.

Boron Nitride Crucible

Commonly used boron nitride types include cubic boron nitride (C-BN) and pyrolytic boron nitride (P-BN). Boron nitride crucibles are usually composed of P-BN. P-BN ceramics have good heat resistance, thermal stability, thermal conductivity, high temperature dielectric strength, and are ideal heat dissipation materials and high temperature insulating materials. P-BN crucibles are often used for smelting metals and semiconductors, and the temperature can be as high as 1800 degrees in vacuum.

Zirconia crucible

Zirconia has a higher melting point than zirconium and is one of the most refractory materials in nature. Even when heated to 1900°C, zirconia will not react with molten aluminum, iron, nickel and platinum metals, silicates and acid slag, etc., so zirconia crucibles can successfully smelt precious metals such as platinum, palladium, ruthenium and cesium and its alloys.

Yttrium oxide crucible

Yttrium oxide ceramic is a high performance ceramic with excellent heat resistance, corrosion resistance and high temperature stability. The melting point of yttrium oxide is greater than 2400 ° C, and it is difficult to react with some active metals (such as Ti, Al, Hf, Nb, etc.) at high temperatures. This crucible has the potential to melt Ti and Ti alloys, or any oxygen-sensitive melting process. However, yttrium oxide has a high melting point and is difficult to process. Since yttrium oxide itself is very brittle, the crucible may crack if heated or cooled too quickly.

High-purity alumina ceramics are tough and versatile technical ceramics. They have excellent thermal and electrical insulation properties. They can be tailored to meet specific requirements.

Small grain size

Heat treatments can coarsen alumina ceramic grains. They are typically performed at temperatures ranging from 1350 degC and 1400 degC. A large increase in grain size decreases the hardness of the Vicker by about 10%. Additionally, the grain size affects cutting techniques, so the smaller the grain size smaller, the better the cutting efficiency.

In light-transmitting applications like high-pressure sodium lamps, arc tubes and other devices for light transmission Aluminas with coarse grain can be employed. Ceramics made of synthetic materials must be resistant to corrosion even at higher temperatures and are transparent, but they also must be able to maintain their strength.

Resistant to corrosion

There are numerous ways to assess the resistance of Alumina Ceramics to corrosion. For example the chemical stability of the material can be assessed by studying its resistance to acids and alkalis. The higher the purity of the material, the better its resistance to these substances. Another method to determine the corrosion resistance of alumina is to test the material in water-based solutions which have a high level of sulfuric acid.

Alumina ceramics are classified by their Al2O3 content. The more of ceramic zirconia the greater the corrosion and wear resistance. Alumina ceramics typically consist of white, granular material that is dense and silky. There are two types of Alumina that are tabular and hydrated.

Machining

Machining Alumina Ceramics is an excellent method to produce high-quality components that have tight tolerances. They are also resistant to chemical, heat and mechanical wear. They are excellent choices for applications in aerospace, medical, and academic industries. They can also be used to make bushings or components with high electrical and corrosion resistance.

Alumina is available in a wide range of purity levels. The range of purity is typically 90 to 99.9%, with Precision Ceramics working primarily with 99.7% alumina. These ceramics are easily extruded and can be molded. However, custom ceramics requires advanced diamond grinding techniques. The most advanced machining techniques have been devised to make this material easier to work with.

Applications

Alumina Ceramics have a broad spectrum of applications in various areas. They are utilized in medical applications as a substitute for bone tissue for orthopedic surgery, for artificial joints and bones, as well as porcelain false teeth.

HOT ALONE WON‘T DO THE TRICK!

HEATING ELEMENTS

About 5000 to 7000 furnaces for sintering zirconia are produced every year at the moment. The numbers are rising. There are two different heating element types that are installed in the dental furnaces on the market to achieve the extremely high temperatures, usually in excess of 1400°C (2552°F). By far the largest share of the furnaces on the market is built with molybdenum disilicide (MoSi2) heating elements. In some few cases, silicon carbide (SiC) heating elements will be used. These two element types differ in their properties in addition to the entirely different basic materials.

SiC heating elements are usually used up to a temperature of 1530°C (2786°F) as recommended by the furnace manufacturer. A firing cycle will take several hours. MoSi₂ heating elements can be used up to a temperature of 1750°C (3182°F), depending on the quality and furnace type. The maximum application temperature of these heating elements therefore is clearly above that of SiC heating elements. Additionally, the surface load, which means the power (W) that can be emitted per square centimeter (cm2) is more than twice that of SiC, at above 25 W/cm2. This permits much faster heating-up rates, to much higher application temperatures. Heating to 1550°C (2822°F) in less than 15 minutes is possible.

MolyCom®-Hyper 1800 (MoSi2) heating elements that have been used on the international dental market since 2005 have turned out to be much longer-lived than SiC elements in continuous tests and according to the experience of various furnace manufacturers. SiC elements usually need to be replaced after just a few hundred cycles due to the strong change of resistance, which corresponds to a service life of approx. 1-2 years at common use. MolyCom®-Hyper 1800 elements in contrast have been operated for more than 2500 cycles without any failure or need for exchange. Exchange of the defective element is usually sufficient in MoSi2 heating elements. In contrast to this, all parts of the SiC elements must be exchanged in one due to the strongly impaired resistance.

If we additionally compare the chemical analysis of the heating elements, the standard heating elements show a much higher degree of contamination, in particular by iron oxide. No contamination could be measured at use of the MolyCom®-Hyper 1800 elements up to a temperature of 1630°C (2966°F). No contamination was measured for MolyCom®-Hyper 1800 Super Clean elements up to 1680°C (3056°F).

Additionally, a contaminated zirconia sample on the surface was analyzed with a secondary ion mass spectrometry (SIMS). As the analysis shows, increased contents of iron oxide could be documented in the sample up to a depth of 0.15 μm. While the degree of contamination is very low, it has a considerable visual effect. The vapor pressures of many different oxides at the surface temperatures of the MoSi2 heating elements in the furnace were additionally calculated with Fact Sage.

Among the ceramic materials, silicon nitride ceramics possess good overall performance (e.g., high hardness, high strength, low density, low thermal conductivity, low chemical activity, and high wear resistance), which promotes these applied as rolling bearing, machine tools, sliding bearing in water pumps.

Aluminum titanate has outstanding properties that make it ideally suited for applications involving molten aluminum, including complete resistance to wetting by aluminum alloys, total gas impermeability, and a very low thermal expansion coefficient. This material offers a longer service life and higher reliability when compared to cast iron, calcium silicate or fused silica components. All riser/stalk tubes are 100% leak-down tested, and parts are available with gasketing and ceramic foam filters to provide complete assemblies.

Alumina ceramic is an industrial ceramic that has high hardness, is long wearing, and can only be formed by diamond grinding. It is manufactured from bauxite and can be shaped using injection molding, die pressing, isostatic pressing, slip casting, and extrusion.

Reaction bonded silicon carbide has excellent wear, impact, and chemical resistance. The strength of RBSC is almost 50% greater than that of most nitride bonded silicon carbides. It can be formed into a variety of shapes, including cone and sleeve shapes, as well as more complex engineered pieces designed for equipment involved in the processing of raw materials.

Ceramic fiber paper is a must-have for those who work in the manufacturing industry. It’s a type of the high-temperature insulated paper that’s integral to many manufacturing functions. For one thing, ceramic fiber paper has a huge variety of applications — whether it’s protecting gaskets (like rope gaskets) from high temperatures or providing insulation — and there’s a range of grades and thermal conductivity, depending on what’s needed. If you’re looking to purchase ceramic fiber paper, we’re your best bet — we’ll discuss some of the benefits and applications that you might not have expected out of this material and what you should expect when ordering and handling it.

One of the major benefits of using ceramic fiber paper is that it has a low thermal conductivity and doesn’t store much heat. It’s also thermal shock resistant and is resistant to most chemicals, which means it has a low corrosion rate. It’s great if you’re looking to die-cut or use automatic stamping and has high dielectric strength as well.

Another benefit to this type of paper is that it’s lightweight and uniform in its structure, which makes it a great type of insulation. It’s also flexible and fire-resistant!

Metal And Non-Metal Oxide Ceramics And Their Properties

Advanced ceramics is a branch of engineering that has been used as solutions to several severe material related problems in the past 30-40 years. Most of these issues are regarding corrosion, erosion, wear and tear, and temperature and electrical insulation of the material. Oxide and non-oxide ceramics in custom steel fabrication have given a way to deal with these problems, resulting in improved yields, life, and manufacturing efficiencies of many industrial processes.

Metal Oxide Ceramics

Alumina (Al2O3) and zirconia (ZrO2) are the most commonly used metal oxide ceramics. Bauxite is the ore from with alumina is extracted and zirconia is produced from zircon, both of which are found in abundance in Australia. Zirconia and alumina are subjected to a process called sintering after being milled to very fine powders. They then transform into extremely hard corrosion-resistant and durable ceramic materials.

Sintering is a process in which materials are subjected to high temperatures, which helps the fine grains to fuse together. This makes the material smoother, decreasing porosity and thereby increasing density.

Properties of Oxide Ceramics

1. Wear resistance 2. Extreme hardness, only negligibly less than that of a diamond. 3. Excellent friction values, even without lubrication or grease. 4. Corrosion resistance 5. High-temperature resistance, meaning that these can be used in furnace construction, for crucibles, and in temperature measurement technology. 6. Electrical insulating properties

Non-Metal Oxide Ceramics

Silicon nitride and silicon carbide are the most frequently used non-oxide ceramics. These have resolved some of the most extreme wear and corrosion problems, regardless of whether high temperature or severe thermal shock is involved. Silicon carbide, favored as a technical ceramic, is used to produce grinding wheels and other products that must perform abrasive procedures. Whereas, silicon nitride is most preferred in thermal shock or other mechanical demands, where a high thermal shock resistance and fracture toughness are needed.

Properties of Non-Oxide Ceramics

1. Extreme hardness, almost close to that of diamond. 2. Oxidation resistance 3. Unique thermodynamic, mechanical, and electrical properties 4. High tensile strength 5. Ensures longer tool life when used with aggressive, high-temperature media. 6. Used in demanding conditions in ballistics, chemical production, energy technology, paper manufacturing, and as pipe system components.

The use of ceramics engineering is increasing as scientists continue to exploit the various properties that composite materials exhibit. This is why ceramics are most preferred in custom steel fabrication as they result in improved hardness, heat, and chemical resistance.
