BN (boron nitride) is a ceramic with excellent lubricity, high thermal conductivity, thermal shock resistance, low coefficient of thermal expansion, chemical stability, and many similarities with graphite, and is also called white graphite.
In addition, while graphite is dielectric, it is a ceramic with high electrical insulation.
It is used in jigs for glass manufacturing, crucibles for metal melting, injection nozzles, electrical insulation parts, and semiconductor manufacturing parts.
