Boron Carbide Powder / B4C Powder (B4C, 1-3um, 99.9%)

Boron Carbide Powder

Boron carbide Powder (B4C chemical formula about) is an extremely tough ceramic boron-carbon, and covalent materials used in tank armor, bullet-proof 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.
Boron carbide was found in the nineteenth century as a by-product of reactions involving metal borides, but its chemical formula was unknown. It was not until 1930 that the chemical composition was estimated as Boron carbide Powder . There was, however, a controversy over the fact that the material did not have this exact 4: 1 stoichiometry, and in practice the material is always slightly weak carbon compared to this formula, and X-ray crystallography shows that their structure is very complex, with a mixture of CBC and icosahedra B12 chains. These features argued against a simple exact empirical formula of B4C. Since the B12 structural unit, the “ideal” boron carbide chemical formula is often not written as B4C, but as B12C3, and carbonic carbide deficiency is described in terms of a combination of units and B12C3 B12CBC.
The ability of boron carbide to absorb neutrons without forming long-life radionuclides makes it as attractive as neutron-absorbing radiation produced in nuclear power plants and neutron-bombs mines. Boron carbide nuclear applications include shielding, control rod, and pellet. Boron carbide is often pulverized to increase its surface.
