Boron nitride composite ceramic material is a composite product of boron nitride and other ceramic materials (such as Si3N4, ZrO2, SiC, etc.), can withstand high temperature above 2000℃, its dielectric strength is more than 40kv/mm. The key technology of the material is uniform compression, uniform heating, reduce excess impurities, make its composite closer or more uniform reaction, extend its service life, ensure its use quality.
Because the material is high hardness, high temperature resistance, and other metal materials are not infiltrated, no pollution, at the same time has excellent mechanical strength, high thermal conductivity and shock resistance, in high-end equipment and special industries have been widely used. In addition to high temperature resistance and lubrication, the material is widely used in the fields of continuous casting separation ring, metal atomizing nozzle, rocket nozzle, amorphous strip and so on. The vacuum conductive ceramic evaporative boat can be made by combining its conductivity with titanium diboride.

HBN Boron nitride composite ceramic materials produced by our company have a unique combination of chemical, electrical, mechanical and thermal properties for a variety of high performance industrial applications. Boron nitride composite ceramic products due to the use of different technical standards are also different, the company can be customized according to user needs of various specifications and raw material ratio of boron nitride composite ceramic products, to ensure the quality of product use.

1. The composite ceramic material with SiO2 and HBN as the main raw material ratio has excellent mechanical strength, high thermal conductivity and heat resistance, but the most important characteristic of this product is the electrical performance of high dielectric strength (>40KV/mm) and low dielectric constant k (<4), so it can be used for rocket and missile antenna window. Antennas to protect radars and other electronic devices.

2. The composite ceramic material with ZrO2, SiC and HBN as the main raw material ratio has excellent wear resistance, no wettability, high thermal conductivity and good high temperature strength. It is most commonly used in molten metal applications such as horizontal continuous casting separation ring, metal atomization nozzles, amorphous product nozzles and side sealing plates for thin strip casting.

3. The composite ceramic material with TiB2, AlN and HBN as the main raw material ratio has excellent high temperature resistance, corrosion resistance and oxidation resistance. It can be used for conductive ceramic evaporation boat for vacuum aluminum plating and crucible for optical coating equipment.
