Boron Nitride

1 Introduction. Boron nitride (BN) is a chemical compound that is isoelectronic and isostructural to carbon with equal composition of boron and nitrogen atoms. The first synthesis of boron nitride was in 1842 by Balmain (1842) using molten boric acid and potassium cyanide; however, stabilizing the material to form powders was a challenge …

Nitride | Chemical Compound, Properties & Uses | Britannica

nitride, any of a class of chemical compounds in which nitrogen is combined with an element of similar or lower electronegativity, such as boron, silicon, and most metals. Nitrides contain the nitride ion (N 3− ), and, similar to carbides, nitrides can be classified into three general categories: ionic, interstitial, and covalent.
