About Boron Carbide

Process of Production :

Boron Carbide is smelted from boric acid and powdered carbon in electric furnace under high temperature. It is one of the hardest man-made materials available in commercial quantities that has a finite melting point low enough to permit its relatively easy fabrication into shapes. Some of Boron Carbide's unique properties include: high hardness, chemical inertness, and a high neutron absorbing, cross section.

Applications :

Boron Carbide is well suited to a variety of industrial applications including:
Abrasives for lapping and ultrasonic cutting, Anti-Oxidant in carbon-bonded refractory mixes, Armor Nuclear applications such as reactor control rods and neutron absorbing shielding.
Wear parts such as blasting nozzles, wire-drawing dies, powdered metal and ceramic forming dies, thread guides.
It is used as an additive in continuous casting refractories due to its high metling point and thermal stability.
