The binary compound nitride is made up of nitrogen and a less electronegativity element. Nitrogen, which has a high electronegativity can form a number of nitrides that include covalent nitrides as well as metal nitrides. onic nitride
Nitrides containing alkali metals or alkaline Earth metals belong to the ionic group. They are crystals with a large proportion of ionic bonding, while the nitrogen element appears as N3+, which is also called salt-like nitrides. Li3N, the only ionic nitride currently used, is a deep red solid. Li3N belongs to the hexagonal crystalline system and is a red solid with a density of 1.27g/cm3 as well as a melting point 813degC. It is very easy to synthesize, and it has a good ionic conductivity. 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 nitrides that are formed from group IIIAVIIA element, and 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 formed by group IIIA elements and IVA (such as AlN, GaN and InN). The unit of structure is similar to that of a diamond tetrahedron, and so is known as class Diamond Nitride. They have a high hardness and melting point. The majority of them are semiconductors or insulators. They are widely used for cutting tools and high-temperature ceramics.

Metal nitride
These nitrides form by transition metals belong to the metallic nitrides. The nitrogen atoms in these nitrides can also be called infill nitrides. The composition of this type nitride can vary, as the chemical formula does not have a strict ratio. Most metal-types nitrides have a NaCl-type structure and the chemical formula MN. In general, it is a metal-like material with properties such as high hardness and melting point, wear resistance resistance, corrosion resistant, etc. It has good prospects for use in cutting materials as well as electrode materials and catalyst materials.
