Hexagonal Boron Nitride Powder
Formula: BN
Molecular weight: 24.84
CAS No.:10043-11-5Hexagonal boron nitride powder is pure, white, ceramic material with lamellar structures similar to graphite. Boron nitride powder has excellent high-temperature stability and lubricating properties, and is a unique combination of high thermal conductivity and dielectric strength in one material.
Physical properties: Density: 2.29g/cm3
