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 are also called salt-like nitrides. They are ionic and formed by metals such as alkali, alkaline, earth, and lithium. 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 solids or liquids. 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 nitrides from group IIIA elements and IVA (such as AlN, GaN and InN). Its structural unit is the same as 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 infills. The composition of this type nitride can vary, as the chemical formula does not have a stoichiometric relationship. Most metal-types nitrides have a NaCl type of structure and their chemical formula is the MN type. 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.
