Hexagonal Boron Nitride Powder
Formula: BN
Molecular weight: 24.84
CAS No.:10043-11-5

Hexagonal 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
Mohs hardness: 2
Thermal conductivity: 40w/m•k

Application:
  1. High-temperature greases;
  2. Release agent for metal molding;
  3. Oils, anti-seize compounds, dielectric greases;
  4. A filler in a variety of resin systems;
  5. BN power can be suppressed in various shapes which are used as insulation and heat sink components at high temperature, high pressure;
  6. Heat shield material in aerospace industry;
  7. It may be converted into cubic boron nitride (CBN) as hard as diamond under the participation of accelerant;
  8. A filler in cosmetics, non-toxic, lubricious, and has a special luster.
