Uses:

• Boron carbide is a hard boron-carbon ceramic material used in tank armor, bulletproof vests, engine sabotage powders, neutron absorber, cutting tools and dies and in brake linings of vehicles. It acts as an antioxidant additives in magnesia-carbon bricks.
• It is used as a precursor in the production of boron containing materials such as titanium borideAbrasive. In the manufacture of hard and chemicals-resistant ceramics or wear-resistant tools. Finely pulverized B4C can be molded under (considerable) pressure and heat. The resulting products are very wear-resistant, such as pressure-blast nozzle liners, thread guides, extrusion dies, and all types of extremely accurate plug, snap, and ring gages. Powder is used as abrasive material, the molded article can be used for wear-resistant material, also used for nuclear reactor.
• It is used for grinding carbide, precious stones and other hard materials, grinding, drilling and polishing, metal boride manufacturing and smelting boron steel, boron alloys and special welding.Boron carbide (B4C) is produced by the hightemperature(about 1371 to 2482°C) interactionof boric oxide, B2O3, and carbon in an electricalresistance-type furnace. It is a black, lustroussolid.
• It is used extensively as an abrasive,because its hardness approaches that of the diamond.
• It is also used as an alloying agent, particularlyin molybdenum steels.
