Diborides have B/M = 2, as in the well-known superconductor MgB 2; they crystallize in a hexagonal AlB 2-type layered structure.Hexaborides have B/M = 6 and form a three-dimensional boron framework based on a boron octahedron (Fig. The basic unit for the crystalline structure of boron is a B 12 icosahedron, with — at each of the 12 vertices — a boron atom bonded to five other atoms. Boron nitride, (chemical formula BN), synthetically produced crystalline compound of boron and nitrogen, an industrial ceramic material of limited but important application, principally in electrical insulators and cutting tools. Boron nitride (BN) nanohorns were synthesized by arc-melting YB 6 powders. The atom consist of a small but massive nucleus surrounded by a cloud of rapidly moving electrons. 6 Citations (Scopus) Overview; Fingerprint; Abstract.
