Hexagonal Boron Nitride ceramic is a material with excellent resistance to high temperature and corrosion, high thermal conductivity, and high insulation properties, it has great promise for development.

The physical and chemical properties of Boron Nitride ceramic

1. Thermal properties: Boron Nitride products can be used in an oxidizing atmosphere at 900℃ and an inert atmosphere at 2100℃. In addition, it has good thermal shock resistance, it will not rupture under the rapid cold and heat of 1500℃.

2. Chemical stability: Boron Nitride and most metals such as solution iron, aluminum, copper, silicon, and brass are not reacting, slag glass is also the same. Therefore, the container made of Boron Nitride ceramic can be used as a melting vessel for the above substances.

3. Electrical properties: Because the dielectric constant and dielectric loss of Boron Nitride ceramic products are low, it can be widely used in devices ranging from high-frequency to low-frequency, it is a kind of electrical insulation material that can be used in a wide range of temperatures.

4. Machinability: Boron Nitride ceramic has a Mohs hardness of 2, which can be processed with lathes, milling machines, it can be easily processed into a variety of complex shapes.

Application examples of Boron Nitride ceramic

1. Depending on the excellent chemical stability of hexagonal Boron Nitride ceramics, they can be used as crucibles and boats for melting evaporated metals, liquid metal delivery tubes, rocket nozzles, bases for high-power devices, molds for cast steel, etc.

2. Depending on the heat and corrosion resistance of hexagonal Boron Nitride ceramics, they can be used to manufacture high-temperature components, such as rocket combustion chamber lining, heat shields of spacecraft, corrosion-resistant parts of magneto-fluid generators, etc.

3. Depending on the insulating property of hexagonal Boron Nitride ceramics, they can be widely used as insulators for plasma arcs and various heaters, as well as high-temperature, high-frequency, high-voltage insulating and heat-dissipating parts.
