High purity 99% Boron Nitride Ceramic Bar Bn insulation block for Electrical Device
Boron nitride crystal belongs to the hexagonal crystal system, its structure is similar to that of graphite, and its performance has many similarities, so it is also called "white graphite".Boron nitride ceramic has good heat resistance,thermal stability,thermal conductivity and high temperature dielectric strength.It is an ideal refractory materials and high temperature insulating material.Boron nitride ceramic does not react with many kinds of metals,ceramic rare earth,and does not pollute the product. It does not crack in quick heating and cooling environment. It can be used in alloy melting, rare earth and ceramic sintering, and also used in electron beam evaporation coating.
