The same number of nitrogen atoms and boron atoms of the bis compound

Boron nitride (BN) is the same number of nitrogen atoms and boron atoms of the double compound, so it is the empirical formula BN. abrasive grinding and carbon are isoelectronic, and the same carbon, boron is cubic boron nitride: the body is similar to one of the graphite-like diamond and the other. Similar to the diamond shape is Synthetic diamond hardest known substance is almost similar to graphite body is a very useful lubricant.
