Boron nitride could be extensively used in the industrial
departments of petroleum, chemical, machinery, electronics,electric
power, textiles, nuclear, space and other. It could be used as the
additives of such polymers as plastic resin and so on, the
insulators of high pressure high –frequency point and plasma are
the solid-phase mixed material of semiconductor, the structural
material of atomic reactor, the packing material for preventing
neutron radiation, the solid lubricant and wear-resisting material
and benzene absorbent etc. The mixture of titanium diboronide,
titanium nitride and boron oxide, which is obtained by hot-pressing
forming of boron nitride and titanium, is 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 powder could be also used
as the stickiness-proof agent for glass microbead, the demoulding
agent for glass and metal forming. The boron nitride made overhard
materials could be used for making the high-speed cutting tool and
the bit of geological prospecting and petroleum.
