▼ Boron Nitride

Boron nitride is a crystal made of nitrogen and boron atoms. The chemical composition is 43.6% boron and 56.4% nitrogen, with four distinct variants: hexagonal boron nitride (HBN), Rhombic boron nitride (RBN), cubic boron nitride (CBN), and wurtzite boron nitride (WBN).

It has good heat resistance, thermal stability, thermal conductivity, high temperature dielectric strength, is the ideal heat dissipation material and high temperature insulation material.

▼ Physicochemical Property

• Material property

Most properties of boron carbide are superior to those of carbon materials. For hexagonal boron nitride: very low friction coefficient, high temperature stability is very good, good heat shock resistance, high strength, high thermal conductivity, low expansion coefficient, very high resistivity, corrosion resistance, microwave or infrared penetration.

• Material structure

Boron nitride hexagonal system crystals, most commonly graphite lattice, but also amorphous variants, in addition to hexagonal type, boron carbide has other crystal types, including: Rhombic boron nitride, cubic boron nitride, wurtzite boron nitride. Two-dimensional boron nitride crystals like graphite have even been found.

▼ Applications

Boron nitride can be used in the manufacture of crucible for smelting semiconductors and high temperature vessels for metallurgy, semiconductor heat dissipation and insulation parts, high temperature bearings, thermocouple bushing and glass forming molds.
