Boron nitride is an inorganic compound with a flat, hexagonal crystal similar to graphite, but with carbon atoms replaced by boron and nitrogen atoms. Chemical formula of boron nitride is BN. Boron nitride can also be in cubic form, wherein alternately linked boron and nitrogen atoms form a tetrahedral bond network similar to carbon atoms in diamond. Cubic boron nitride, c-BN, is the second hardest material after diamond; however, it does not chemically wear in the presence of graphite and/ ... Read more
