Boron Carbide

Boron Carbide (chemical formula approximately B4C) is an extremely hard boron–carbon ceramic and covalent material used in tank armor, bulletproof vests, engine sabotage powders,as well as numerous industrial applications. With a Vickers hardness of >30 GPa, Boron Carbide Abrasive Powder is one of the hardest known materials, behind cubic Boron Nitride and diamond.

Boron Carbide Powder was discovered in the 19th century as a by-product of reactions involving metal borides, but its chemical formula was unknown. Boron Carbide Applications Boron Product was not until the 1930s that the chemical composition was estimated as B4C.Controversy Boron Carbide Buy remained as to whether or not the material had this exact 4:1 stoichiometry, as, in practice the material is always slightly Titanium Dioxide carbon-deficient with regard to this formula, and X-ray crystallography shows that its structure is highly complex, with a mixture of C-B-C chains and B12 icosahedra.

These features argued against a Pvc Resin very simple exact B4C empirical formula.Because of the B12 structural unit, the chemical formula of "ideal" boron carbide is often written not as B4C, but as B12C3, and the carbon deficiency of boron carbide described in terms of a combination of the B12C3 and B12CBC units.
