Boron Carbide (B4C)

Boron Carbide is a very hard ceramic of carbon and boron. It is one of the hardest known materials known to science, only surpassed in harness by cubic boron nitride and diamond. The structure of this ceramic consists of C-B-C chains, icosahedra of B12, and octahedron of B6, and so technically B4C though given a common name, is a gross underrepresentation of the material’s structure. Applications for this material typically utilize its strength, seeing wide use as tank armor, bulletproof vests, and engine sabotage powders. Additionally, as a semiconductor, it utilizes hopping transport as opposed to band transport, and although its estimated band gap is 2.09eV, the bandgap depends on composition as well as the degree of order. Moreover, Boron Carbide efficiently absorbs neutrons, making it a valuable material in nuclear reactors as a control material.
