Boron Nitride Ceramics:
Boron nitride is a crystal composed of a nitrogen atom and a boron atom. The chemical composition is 43.6% boron and
56.4% nitrogen with four different variants: hexagonal boron nitride (HBN), rhombohedral boron nitride (RBN),
cubic boron nitride (CBN) and wurtzite nitrogen. Boron (WBN).
Boron Nitride Ceramics properties:
Boron nitride ceramics have good heat resistance, thermal stability, thermal conductivity, high temperature dielectric strength,
and are ideal heat dissipation materials and high temperature insulation materials.
Boron nitride has good chemical stability and is resistant to most of the molten metal. It also has good self-lubricating properties.
Boron nitride products have low hardness and can be machined with an accuracy of 1/100 mm.
