Boron Nitride Crucible – Perfect For Extreme Heat Applications
High-purity boron nitride crucibles are essential tools for thermal processes such as materials synthesis and crystal growth, offering exceptional heat resistance and chemical inertness to protect processed materials from contamination while keeping them pure.
Boron nitride stands out from zirconia as an ideal material for use in crucibles due to its resistance to strong chemicals and extremely hot temperatures, along with having low thermal expansion compared to other ceramics. It provides greater stability.
High Temperature Resistance
Hexagonal boron nitride (h-BN) crucibles offer superior temperature management in applications requiring precise temperature control such as crystal growth and material processing. They don’t oxidize or degrade at elevated temperature ranges, making them highly durable and long-lasting crucibles suitable for precise temperature regulation like crystal growth. This feature makes them especially valuable tools.
Thermal shock resistance is also key for various applications; for instance, they can quickly be cooled from 1800 degrees to ambient without cracking and can even withstand being held in a 1000 degree furnace for 20 minutes without showing signs of damage.
H-BN crucibles are chemically inert, meaning that they do not react with any materials used in high temperature processing, making them especially advantageous in applications like aluminum melting and casting as well as semiconductor manufacturing. While certain substances such as antimony trioxide, chromium hexaoxides, molybdenum trioxides, arsenic trioxide titanium carbide glazes may corrode this type of material, the rest should remain safe to be exposed directly.
Excellent Chemical Inertness
Boron nitride’s low thermal expansion and high dielectric strength makes it an excellent material for electrical insulation, which lowers the risk of cracking in hot environments. Furthermore, its chemical inertness and corrosion resistance make it suitable for use across a range of applications.
Boron nitride can come in various crystalline forms, with hexagonal boron nitride being one of the more frequently utilized varieties. This material possesses properties similar to graphite that give it lubricating qualities, reducing friction and wear on machinery.
PBN crucibles are ideal for high-temperature processes like ceramic melting, silicate melting, metal smelting and crystal growth experiments that require high temperatures. Durable and resistant to chemicals, their surfaces do not stick easily thereby eliminating contamination and providing accurate results. Furthermore they’re easy to clean while offering great heat transfer – qualities vital for many applications.
High Flexibility
Boron nitride’s special ability to withstand high temperatures while remaining an inert environment enables it to be used in many thermal processes that would otherwise not be possible, including those related to production of pure, consistent products. Due to this inertness of BN during production processes and products development processes, contamination during production processes can be minimized while product purity can remain constant and assured.
Boron nitride stands out as both chemically inert and mechanically strong. It does not react with most metals, ceramics, and other materials used for high temperature processing crucibles, making it the ideal material choice.
Boron nitride’s intractable structure renders it resistant to high-temperature and chemical stresses, and comes in various polymorphs such as hexagonal boron nitride (hBN), rhombohedral boron nitride (RBN), cubic boron nitride (CBN) and Wurtzite boron nitride. Each form offers unique properties that benefit a range of applications; for instance hBN boasts excessive lubricating properties while electrical conductivity levels similar to diamond; while cubic forms are used extensively in cutting tool bits and grinding gadgets.
Excellent Moisture Resistance
Boron Nitride crucibles are long-lasting and versatile tools suitable for high temperature applications such as Metal Ingot Casting, Physical Vapor Deposition (PVD), Chemical Vapor Deposition (CVD), etc. They transfer heat efficiently, resist chemicals without sticking, and don’t allow materials to stick onto them – essential features in high temperature work environments.
Hexagonal boron nitride (h-BN) is an extremely dense and machineable material, making it perfect for producing customized crucibles of all sizes or shapes. Hot pressing and sintering techniques allow product blocks to be formed according to customer specifications before being finished off by shaping or finishing operations.
h-BN differs from graphite in that it can withstand corrosion at high temperatures without reacting with liquid salts, making it an excellent choice for precious metal smelting and nanomaterial synthesis processes. Furthermore, its resistance against fast cooling temperatures of 1500degC and furnace holding, blowing, rapid quenching at 1000degC allow it to withstand hundreds of continuous cycles without cracking under pressure.
