Background
Boron Carbide is a high
performance abrasive material with chemical and physical properties similar to
diamonds, such as, chemical resistance and hardness. Boron carbide`s extra
hardness gives it the nickname "Black Diamond" (It ranks third after diamond and
boron nitride) and is one of the leading grinding materials.
Application examples
- Grinding, lapping and polishing tungsten carbide and other hard materials
such as different types of ceramics, minerals, glasses, etc
- Hot pressing and sintering of the hard and abrasion resistant parts with
super light weight.
- Metallurgical refractory with high corrosion and oxygen resistance.
- Neutron absorbing materials for nuclear technology.
- Additive for sintering silicon carbide parts and diamond tools.
- Steel modification component with high boron content.
