Refractory materials:
As antioxidant additives in refractory field.

Ceramics materials:
As materials made of boron carbide products and wear resistant components using in Blasting, Sealing, Machinery, Ships, Auto, Dies, Aviation and Aerospace industries.

Armor tiles:
High density boron carbide armor tiles, bullet proofing seats of helicopters.

Nuclear industry:
Boron carbide is an important material for nuclear applications due to high absorption cross section.

Boriding Agent:
Boron carbide is a raw material used in boriding agent. After the treatment, The hardness and the wear resistance of the surface are greatly improved.

Chemical additives:
Because of boron carbide good chemical resistance, for producing other boron containing materials such as titanium boride or zirconium boride.

Solid fuel:
Boron carbide based propellants for ducted rockets.
