Product features
This product has high purity, small particle size, uniform distribution, large specific surface area, high surface activity and low packing density. Is a kind of artificial synthesis super hard material, is one of the most hard artificial abrasives, has the stable physical and chemical properties, non-magnetic, resistant to high, low temperature, strong acid, strong alkali. The hardness is second only to diamond. As an abrasive, it has very high grinding efficiency and is an ideal substitute material for diamond. In addition, boron carbide can effectively absorb neutrons without releasing gamma rays that are harmful to human body, thus preventing secondary radiation pollution.

Application field
1 nanometer boron carbide powder has higher neutron absorption efficiency than micron boron carbide powder, so it is widely used in nuclear industry and national defense industry.
2. Adding boron carbide bullet-proof armor made of nano-boron carbide powder, the mechanical properties and anti-penetration ability are greatly improved, and the armor protection ability is more prominent;
3 nanometer boron carbide powder is not only used in refractories and precision measuring elements, but also used in manufacturing high precision nozzles, sealing rings and other fine engineering ceramics.
4 nanometer boron carbide powder is a kind of synthetic superhard material. As an abrasive, it has a very high grinding efficiency and does not bring impurities, so it is an ideal substitute for diamond abrasive.
High grade refractory materials, fine engineering ceramics, such as high precision nozzle, sealing ring, nuclear industry, national defense industry.

The packing storage
This product is inert gas anti-static packaging, should be sealed in a dry, cool environment, should not be exposed to the air for a long time, prevent moisture agglomeration, affect dispersion performance and use effect.
