Boron Carbide : Boron carbide is smelted from boric acid and powdered carbon in electric furnace under high temperature. It’s an extremely hard material with dark grey or black color. Due to the premium characters of boron carbide, it is a perfect material for many different industries.

Boron Carbide finds extensive applications in the Hard Metals (Carbides) industry, in the production of Tools & Machine Components, in Finishing/Lapping of numerous items, in ultrasonic drilling, in nuclear reactors for neutron absorption as an antioxidant in refractories, in welding for manufacturing hard facing electrodes and also in rocket propellants and armoured plates.
