Boron carbide - Wikipedia

Boron carbide (chemical formula approximately B 4 C) 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, it is one of the hardest known materials, behind cubic boron nitride and diamond. History. Boron carbide was discovered in the 19th ...

3M™ Boron Carbide Powder

3M™ Boron Carbide Powders considerably extend the service life of modern refractories used in steel production equipment. The corrosion of alumina-carbon refractories is controlled by the oxidation of the carbon structure. While carbon-bonded compositions have the best chemical resistance against molten steel and slag, they are also sensitive to oxidation. Compared to conventional metal ...

Boron Carbide (B4C) - Properties and Information about ...

09/02/2001  Boron carbide powder (see figure 1) is mainly produced by reacting carbon with B 2 O 3 in an electric arc furnace, through carbothermal reduction or by gas phase reactions. For commercial use B 4 C powders usually need to be milled and purified to remove metallic impurities. In common with other non-oxide materials boron carbide is difficult to sinter to full density, with hot pressing or ...

Reade Advanced Materials - Boron Carbide Powder (B4C)

Boron carbide was discovered in the 19th century as a by-product of reactions involving metal borides, however, its chemical formula was unknown. It was not until the 1930s that the formula was determined to be B4C.[1] Boron carbide is now produced industrially by the carbo-thermal reduction of B2O3 (boron oxide) in an electric arc furnace.

Boron Carbide - an overview ScienceDirect Topics

The nominal boron carbide stoichiometric formula is B 4 C; however, it has a very wide phase stoichiometric range from B 4 C up to B 10.5 C. Boron carbide powder is produced commercially using either (1) fusion, which involves a reduction of boron anhydride (B 2 O 3) with carbon (endothermic); or (2) magnesiothermy, in which boron anhydride reacts with magnesium in the presence of carbon
