Basic characteristics of high temperature boron nitride series

Basic characteristics of high temperature boron nitride series

1. High temperature stability: the melting point of inert gas can reach 3000 °C, and the oxygen resistance can reach 900 °C under air.

2. Non-wetting to metal: Suitable for all kinds of metal alloys坩埚

3. Lubrication characteristics: Hexagonal boron nitride, also known as white graphite, has excellent lubricating properties and is widely used in lubricating oils and mold release agents.

4. Boron nitride is a chemically inert material that is stable at 2700 ° C under argon.

5. High thermal conductivity: The heat conduction in X/Y direction can reach 400w/m*k, which is the best insulating and thermal conductive material.

6. Low dielectric constant and dielectric loss

 

typical application:

1. Solid lubricant at high temperature

2. Release agent in casting molding and injection molding

3. Raw materials for the production of cubic boron nitride

4. For the preparation of composite ceramics, such as vacuum aluminum plating evaporation boat

5. For electrical insulation

6. For thermal plastics, thermal silicone gaskets, etc.

7. Metal forming and drawing lubricant

8. Thermal shielding materials in the aviation industry

9. Compressed into various shapes of high temperature, high voltage, insulation, heat sink parts
