BN is smooth soft powder in white color. Due to the similar platelet structure with graphite, BN shows similar properties with graphite, so it is called “white graphite”. It provides perfect electricity insulativity, thermal conductivity, lubricity and chemical resistance. It has also strong neutron absorption ability. It is chemical inert materials, stable in the air at 1,000℃ and in argon even to 3,000℃. Its powder could be made into parts after hot pressed which is easy to machining. Such BN parts are stable even at 2000℃.
Grade HC was produced at 1,600-1,800℃, with good high temperature resistance and oxidation resistance performance. Its original size is small and reunited size is large. Due to its round reunited particle shape, it is to be applied as filler or release agent when shape casting and injection molding. It is also used to produce composite ceramic and hot press BN parts.
Our company is the sole Chinese BN manufacturer who produces high crystallinity Hexagonal Boron Nitride (h-BN). High crystallinity h-BN provides better thermal conductivity, insulativity, lubricity, higher temperature proof and chemical resistance ability than normal products. Grade HN was produced at 1800-2000℃, its performance approaches or achieves imports, which could substitute the imports. The particle size of Grade HN was uniform and similar with PTFE, so, it’s better to be used to make high-voltage switch spout. And meanwhile, due to its excellent thermal conductivity, it is particular to be used in thermal conductive plastic and rubber. Further more, it is also good to be used as the raw material of special ceramic because its low oxygen level which is often 0.5% max.
Grade HS was also produced at 1800-2000℃ with high crystallinity and more uniform size. High crystallinity h-BN provides better thermal conductivity, insulativity, lubricity, higher temperature proof and chemical resistance ability than normal products. So, it could be used in many high-quality areas which include cosmetic and thermal conductivity material. Its performance approaches or achieves imports, which could substitute the imports.
