Products made of grinding tungsten steel should be used Boron carbide150#、800 #
Tungsten steel material has high hardness, and boron carbide is a relatively high material in abrasives. Therefore, boron carbide has a good grinding effect on tungsten steel.
Features of boron carbide
The product has high purity, small particle size, uniform distribution, large specific surface area, high surface activity, low bulk density, is a synthetic super-hard material, the hardness is second only to diamond, with stable physical and chemical properties.
Application areas of boron carbide
1nm boron carbide powder also has a higher neutron absorption efficiency than micron-sized boron carbide powder, so it is widely used in the nuclear industry and defense industry;
2 Boron carbide bulletproof armor made of nano boron carbide powder is added, the mechanical properties are greatly improved, the anti-penetration ability is greatly improved, and the armor protection ability is more prominent;
3nm boron carbide powder is not only used in refractory materials, precision measuring elements, but also used to manufacture high-precision nozzles, sealing rings and other fine engineering ceramic products;
4nm boron carbide powder is a synthetic superhard material, as an abrasive, it has extremely high grinding efficiency and will not bring impurities, which is an ideal substitute for diamond abrasives;
5 Refractory materials, fine engineering ceramics, such as high-precision nozzles, sealing rings, nuclear industry, defense industry.
Packaging storage of boron carbide
This product is inert gas anti-static packaging, should be sealed and stored in a dry, cool environment, should not be exposed to air for a long time, to prevent moisture agglomeration, affecting the dispersion performance and use effect.
Key points of boron carbide material production:
1) Reduction of sintering temperature;
2) Improvement of strength and fracture toughness;
3) Improvement of antioxidant behavior.
Structure determines performance is an eternal law of nature. For the new boron carbide material system, its performance depends on the microstructure structure, and the formation of the microstructure is closely related to the chemical composition, winding process and phase reaction process. In view of the characteristics of boron carbide ceramics and the importance of bulletproof armor ceramics, Jingdezhen Special Ceramics Research Institute has studied new boron carbide-based superhard bulletproof ceramic materials and achieved good results in a series of work from raw material formulation, sintering process to finished products and performance testing. The developed high-performance B4C ceramics have reached the enterprise standard and the US military standard, and its technical level has filled the domestic gap, advanced level, and provided China with a new type of lightweight high-performance bulletproof armor products.
