Hexagonal boron nitride is a synthetic non-oxide ceramic material. It has a similar crystal structure to graphite, also known as “white graphite”.
Due to the strong covalent bond in the boron nitride molecule, compared with traditional metal materials and polymer materials, it has many excellent properties:
Formula: BN
Molecular weight: 24.84
CAS No.：10043-11-5
Physical properties:
Density: 2.29g/cm3
Mohs hardness: 2
Thermal conductivity:45w/m•k
Advantages of boron nitride powder：
(1) Excellent high temperature resistance;
(2) Excellent thermal performance;
(3) Good oxidation resistance;
(4) Stable friction performance;
(5) BN also has low density, high resistivity, high dielectric performance, excellent wave permeability performance, good processability, chemical corrosion resistance, and a variety of metal is not moisten and other excellent physical and chemical characteristics.
