With a Vickers Hardness of GPa, it is one of the hardest known materials, behind cubic boron nitride and diamond. You can help by adding to it. With a Mohs hardness between and 1 boron carbide is one of the hardest synthetic substances known, being exceeded only by cubic boron nitride and diamond.
As an abrasive, it is used in powdered form in the lapping (fine abrading) of metal and ceramic products, though its low oxidation temperature of 400–500° C . A high performance abrasive material with chemical and physical properties similar to diamonds, such as chemical resistance and hardness.
Color is black or gray. This Boron- Carbon substance ranks only after diamond and cubic Boron Nitride in the list of hardest materials. It is sometimes called the “Black Diamond” for its extreme hardness.
Boron carbide (chemical formula B4C) is an extremely hard ceramic material used in . Washington Mills manufactures boron carbide (B4C) – one of the lightest, hardest, chemically inert, man-made materials with a finite melting point and a high. It has many industrial applications, but machining it to final tolerances is a specialized process best left to experts like Insaco. Hot-pressed boron carbide is one of the hardest materials available in commercial shapes, and gives outstanding resistance to abrasive . Continue reading “Boron carbide”
