Structure: Boron Carbide has a rombohedral crystal structure and that is common to icosahedron-based mostly borides. It can accommodate a number of Carbon compositions (as many as B10C) without the need of modifying its very own structure.The earliest electrical application of SiC was like a surge safety in lightning arresters in electric electric
