Products Descripition
Boron carbide powder from China B4C F400 F500 F600 F800 microns
Boron carbide or B4C is an excellent wear-resistant and high-temperature resistant synthetic material. Boron carbide is produced by high-temperature smelting of boric acid and carbides into blocks, followed by crushing and sorting. It has high hardness, moderate grinding force, low specific gravity, and strong neutron shielding ability against radiation substances. Therefore, it can not only be used for wear-resistant materials and grinding media, but also as one of the main raw materials for boron carbide wear-resistant ceramics and nuclear industry protective materials.
