2. Applications
Boron nitride could be extensively used in the industries of petroleum, chemical, machinery, electronics, electric, textiles, nuclear, space and other. It has been used as the additives of plastic resin, the insulators of high-voltage high-frequency point and plasma arc, the solid-phase mixed material of semiconductor, the structural material of atomic reactor, the packing material for preventing neutron radiation, the solid lubricant, wear-resisting material and benzene absorbent, etc. The mixture of titanium diboride, titanium nitride and boron oxide, which is obtained by hot-pressing forming of boron nitride and titanium, is used as the catalyst for dehydrogenation of organic matters, rubber synthesis and platforming. In high temperature, it could be used as the specific materials of electrolysis and resistance, and hot sealing dry-heating agent of transistor. It is the material of aluminum evaporating container. The powder could be also used as the abherent for glass microbead, the release agent of molding glass and metal.
