Boron Nitride Powder Description

Boron nitride powder is an advanced boron nitride ceramic material available in solid and powder forms. BN powder has high heat capacity, outstanding thermal conductivity, easy machinability, lubricity, low dielectric constant and superior dielectric strength. These properties make boron nitride powder a truly outstanding ceramic material and can be used in high-temperature environments.

BN is also referred to as white graphite. Boron nitride powder is a non-abrasive, white powder with a hexagonal platy crystal structure similar to graphite, but with a much higher oxidation resistance at 800 C. Boron nitride ceramic powder has high thermal conductivity, low coefficient of friction, high dielectric constant and are chemically inert. Due to those unique properties, it is used in a broad range of applications ranging from electronics, aerospace, oil and gas, ceramic manufacturing, and cosmetics.

Boron Nitride Powder Advantages

- Low wettability to molten metal
- Relatively high thermal conductivity with low thermal expansion
- Relatively high thermal shock resistance
- Extremely high working temperature with proper inert gas protection (>3000C has been recorded).

Boron Nitride Powder Applications

Hexagonal boron nitride powder can be used:
- In the fabrication and luminescence study of monolayered boron nitride quantum dots.
- Rare earth boron complexes.
- Boron nitride filled polybenzoxazine system as a thermally conducting molding components for electronic packaging applications.
- Boron containing ceramic products.
- As a starting material to form boron nitride nanotubes.
- To load silicone rubber and its consecutive effect on its thermal, mechanical and morphological properties was studied.
