Boron nitride (BN) insulators can withstand high temperature use; in inert or vacuum conditions they can be used continuously up to 2100℃ without degradation. In the air, they maintain stability up to 1000℃. Thus, BN insulators achieve high-temperature insulation that conventional insulators would be incapable against.
BN insulators have excellent dielectric strength (20 – 40 kV/mm); high volume resistivity (> 1014 Ω·cm); and low dielectric loss. These attributes support the performance of BN insulators as high voltage and high frequency electricity barriers in adverse conditions.
Yes, BN insulators are very chemically inert. They can resist most molten metals, any acid and alkali without suffering structural damage, and maintain structural integrity even in severe chemical conditions.
BN insulators are used widely in high temperature furnaces, vacuum systems, aerospace, and semiconductor applications (e.g., components of MOCVD). They typically provide the preferred solution to complex problems in those applications because of the excellent characteristics of chemical resistance, electrical insulation, and thermal shock stability that are available.
