The binary compound nitride is made up of nitrogen and an element which has a lower electronegativity. Nitrogen, which has a high electronegativity can form nitrides when combined with other elements that have a lower electronegativity. This includes ionic nitrides as well as covalent and metal Nitrides. onic nitride
Nitrides consisting of alkali metals, alkaline Earth metal elements, and nitrogen are known as salt like nitrides. Li3N, the only ionic nitride currently used, is a deep red solid. Li3N belongs to a hexagonal crystal system and is a red solid with a density of 1.27g/cm3 at a melting temp of 813degC. It is very easy to synthesize, and it has high ionic conduction. It can be combined either with liquids or solids. Coexistence of Lithium is one of best solid lithium electrodes currently available.

Covalent nitride
Covalent nitrides are formed when group IIIAVIIA element are combined. The majority of their crystals consist of covalent bonding. Nitrogen oxides and nitrogen halos are the correct names for compounds that oxygen, group VIIIA elements and nitrogen form. The covalent nitrides most commonly used are mainly the nitrides from group IIIA elements and IVA (such as AlN, GaN and InN). The unit of structure is similar to that of a tetrahedron, and so is known as class Diamond Nitride. They are hard, have a high melting temperature, and exhibit good chemical stability. The majority of them are semiconductors or insulators. These materials are widely used for cutting tools, high temperature ceramics, microelectronics, and luminescent substances.

Metal nitride
These nitrides form by transition metals belong to the metallic nitrides. The nitrogen atoms in these nitrides can also be called infill metal nitrides. This type of metal-type nitride is not a stoichiometric nitride, but its chemical composition may vary in a given range. Most metal-types nitrides have a NaCl type of structure and the chemical formula MN. In general, it is a metal-like material with properties such as high hardness and melting point, corrosion resistance and wear resistance. It has great potential for use in cutting materials as well as electrodes and catalytic material.
