Applications

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 boride.

Notes

Store away from the sources of heat and direct sunlight. Incompatible with strong oxidizing agents.
