Note: We can supply different size products of boron carbide powder according to client's requirements.
High purity, small particle size, uniform distribution, large specific surface area, high surface activity and low bulk density. It is a synthetic superhard material with hardness second only to diamond. As an abrasive, it has extremely high grinding efficiency. It is an ideal substitute for diamonds.
Application of boron carbide powder:
1. Refractory: B4C powder is used for anti-oxidation in carbon-containing refractories, which can densify products, prevent carbon oxidation in carbon-containing refractories, reduce porosity, increase medium-temperature strength, and reduce cracks.
2. Nuclear industry: This product has higher neutron absorption efficiency than micron, so it is widely used in nuclear industry and national defense industry. The use of B4C material as the isolation block enables the storage pool that can meet the 15-year storage period to meet the requirements of the International Atomic Energy Agency for the temporary storage of spent fuel for a minimum of 50 years.
3. Military business: Adding the bulletproof armor of nano B4C, the bulletproof board has high hardness and small specific gravity; the mechanical performance and penetration resistance are greatly improved, and the armor protection ability is more prominent.
4. High-precision nozzle: Due to its light weight and high hardness, nano B4C is widely used in the production of hand-held sandblasting machine production nozzles, hydraulic cutting nozzles, etc. B4C ceramic nozzles have long life and small dimensional changes.
5. Abrasives: Nano B4C powder is a kind of artificial superhard material. As an abrasive, it has a very high grinding effect and does not bring impurities. It is an ideal substitute for diamond abrasives.
6. Grinding medium: The grinding ball prepared by isostatic pressing of nano-B4C is second only to diamond, so it can be used as a grinding medium for almost all grinding occasions except diamond.
7. Sealing ring: Nano B4C ceramics are used to prepare sealing rings. Due to their high hardness and high corrosion resistance, they are widely used in conveying pumps containing a large amount of solid particle liquid. Their service life can reach more than one year. Ideal material for occasional sealing
Storage conditions:
boron carbide powder should be sealed and stored in a dry and cool environment. It should not be exposed to the air for a long time, to prevent agglomeration due to moisture, affecting the dispersion performance and use effect, and should avoid heavy pressure, do not contact with oxidant, and transport according to ordinary goods.
