Boron Nitride Crucible Excellence in High Temperature Applications
Boron Nitride Crucibles offer outstanding thermal stability for consistent heat dispersion, helping reduce temperature gradients and providing reliable processing results. Their chemical inertness allows them to be used even in caustic environments for material processing or crystal growth processes.
Contrary to alumina, aluminum doesn’t react with molten metals and salts in the environment, thus protecting its final product and prolonging its lifespan.
High Thermal Conductivity
Boron nitride (hBN) is a high-purity material with excellent thermal and chemical inertness that makes it suitable for various applications requiring stable containers that won’t degrade during processing, such as high-temperature experiments and materials processing processes requiring sturdy containers without degrading during the process.
HBN is commonly found in kilns and furnaces for its rapid cooling capability at ambient temperatures without cracking or breaking, and can withstand extreme temperatures without cracking or breaking; its extreme temperatures resistivity allows it to be blown, melted, quenched, re-heated repeatedly without losing strength. Furthermore, this material exhibits very low wettability by most substances including metals, rare earth metals, precious metals, semiconductor materials glass and molten salt which make it suitable for wafer processing applications as it impervious to oxygen making it ideal for wafer processing applications.
hBN can easily be machined into customized shapes for various high-temperature uses, including LEC-type crucibles for growing high-grade gallium arsenide crystals and VGF-type containers for growing large germanium crystals for LED displays. Both keep temperature steady while protecting from defect formation.
Low Coefficient of Thermal Expansion
Hexagonal Boron Nitride (hBN) is an easily workable material and can be hot-pressed into custom shaped products like crucibles with ease. Once formed, HBN material possesses high resilience against temperature extremes and stresses without deforming or cracking; additionally it boasts low coefficient of thermal expansion along its c-axis.
These unique properties make pBN an excellent material choice for applications requiring high temperature stability, chemical inertness and electrical insulation. Common applications of pBN include scientific research and materials science experiments in controlled environments that must withstand extreme conditions.
Additionally, these mats can withstand erosion from metal liquids and do not react with many chemicals such as aluminum and titanium oxide, making them useful in oxygen sensitive applications to hold metals, rare earth materials, fluorides, glass silicon, and molten salt. Furthermore, their rapid material change capabilities enable short cycle times and higher overall yields; their stability up to 2000degC ensures stability under either non-oxidizing or reducing atmospheres, and they provide thermal shock resistance as well.
Excellent Chemical Inertness
Hexagonal boron nitride is chemically inert towards molten metal, making it ideal for use as a crucible in melting and casting processes. This makes boron nitride superior to graphite as the latter can interact with it and introduce impurities into final products, while resisting oxidation occurring under high temperature environments.
Oxidation can wreak havoc on materials, leading to their degradation and ultimately leading to their collapse. However, BN crucibles are equipped to handle oxygen rich environments without producing oxides and are an excellent choice for applications which rely heavily on oxygen for functionality or integrity.
BN crucibles are indispensable tools in high-temperature processes such as crystal growth, ceramic sintering and material research. Their versatility extends beyond these processes into semiconductor manufacturing, metal smelting, glass melting and chemical processing applications due to their exceptional thermal stability, resistance to chemical reactions and non-wetting properties – not forgetting they can even be machined into various shapes for accommodating specific deposition techniques and power sources.
Excellent Oxidation Resistance
Boron nitride (BN) is an ideal material for high-temperature applications like crystal growth, materials research and ceramic sintering. Withstanding temperatures up to 2000degC without suffering structural changes means BN crucibles can help preserve the integrity of processed materials.
Boron nitride not only offers superior heat resistance, but it’s also chemically stable and offers low thermal expansion – two features which make it suitable for use with various substances, including liquid metals and harsh chemicals.
Boron nitride differs from graphite in that it does not oxidize at high temperatures and remains highly resistant to metals, oxides and corrosive substances such as antimony oxide, chromium oxide, molybdenum trioxide and arsenic trioxide which would oxidize at such temperatures.
Our boron nitride crucibles are carefully packaged to minimize damage during storage and transportation. Sealed bags are placed into carton boxes lined with heavy foam for safe handling; this special packaging helps us ensure the quality of our products; in most cases they arrive back at clients exactly in the condition in which they left our facility.
