Grade HC/HC-W

Formula: BN, CAS No.: 10043-11-5, smooth soft powder in white color. Its microstructure is single platelet with hexagonal crystal system. It provides perfect electrical insulation, thermal conductivity, lubricity as well as chemical resistance. It is chemical inert material; almost stable to all the organic solvent, melting metal and corrosive chemicals.

Applications
 
  ★ To produce special composite ceramic such as Evaporation Boat
  ★ As the raw material for hot pressed BN
  ★ As additive of lubricant coating
  ★ As additive of metal surface treatment
  ★ To produce Cubic Boron Nitride
  ★ As the release agent in shape casting or injection molding process
  ★ As additive in high temperature lubricant oil
 
Characteristics
 
Grade HC is a medium crystal sized with good high temperature resistance and oxidation resistance performance. The crystal size is smaller and some agglomerate to particles with larger size. Due to its round partial agglomerate particle shape, it is very suitable for the application of filler or release agent in shape casting and injection molding process. It is also used to produce composite ceramic and hot pressed BN parts.
Grade HC-W has lower B2O3 content, so it is the perfect choice for the applications that request lower B2O3 contents.
