Product Description

Industrial Machinable BN boron nitride ceramic Components

The main features of the boron nitride ceramic parts

1. High thermal conductivity than aluminum oxide (aumina) ceramics, up to 35 W/mk.

2. Excellent thermal shock resistance which is smilar to graphite and chemical stability.

3. Good electrical insulation, even if under humidity and high temperature working conditions.

4. Easily machinable characteristic, it's easier to achieve a high precision accurancy, such as 0.01mm.

5. Not wetted by most molten metal, slag and glass, it can be used a container for metaling glass and metal.

The description of boron nitride ceramic components

Boron nitride (BN) is an advanced technical synthetic ceramic material which has exceptional temperature resistance, dielectric strength and thermal conductivity. Furthermore, boron nitride is an easily machinable material and can be machined desirable geometries thanks to similar properties as graphfite. In addition, BN owns lubrication capacities.

The boron nitride ceramic components we supply include boron nitride ceramic plates, boron nitride ceramic sheet, boron nitride ceramic rod, boron nitride ceramic crucible, boron nitride ceramic structure ceramic parts and so on.

The application of boron nitride ceramic components

Boron nitride ceramic parts are widely used as Protection and sheathing for thermocouples and measuring probes, electrical insulation at very high temperatures, smelting and sintering crucibles, solar and photovoltaic industry, Ceramic Tubes and insulation sleeves in furnace, ceramic supports & nozzles in soldering and brazing application, PVD installations and so on.
