Hexagonal Boron Nitride
Grade HC

Introduction:
Formula: BN, CAS No.: 10043-11-5, 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 2,000℃.

Typical Applications:
◇To produce cubic boron nitride
◇As the raw material of Evaporation Boat
◇To produce hot press ceramic parts
◇As the raw material of special ceramics
◇As the release agent when shape casting or injection molding

Characteristics:
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.
