These nitrides are formed from alkali and alkaline elements and belong to the ionic group. They have mainly ionic crystals. There is a nitrogen element in the form N3- which is sometimes called salt-like and nitrides. Li3N can be used for ionic nutrides at the moment. Li3N is an opaque red solid that belongs to the hexagonal crystalline system. It has a density at 1.27g/cm3 as well as a melting temperature of 813degC. It’s easy to produce and exhibits high ionic conducting power. Lithium can be mixed with either liquid or solid. It is the best-known solid lithium electrolyte.
Covalent nickel
Covalent nitrides are formed from group IIIAVIIA element elements. The crystals of these nitrides are made mainly by covalent bonds. They should also be known as nitrogen oxides, nitrogen halides, and compounds that are formed from oxygen, group VIIA and nitrogen elements. Covalent nitrides that are most commonly used include those made from nitrides of IVA and group IIIA elements, such as BN and AlN. This structural unit has a similar structure to that of a Diamond’s Tetrahedron, and is therefore also known as class Diamond Nitride. They are hard, very melting and have good chemical stability. Many of these are semiconductors and insulators. These are commonly used in cutting instruments, high-temperature Ceramics, microelectronics devices, and luminescent Materials.
Metal Nitride
Metal nitrides include nitrides made of transition metals. They contain the nitrogen atoms in close-packed metal gaps. Also known as infill nitrides. These nitride chemical formulas do not have a set stoichiometric proportion. The composition of these nitride types can be varied within certain limits. Metal-type nitrides tend to be of NaCl or MN structure. It generally has metallic luster, good conductivity and high melting point. Wear resistance and corrosion resistance are also some of the metal-like qualities. This material is well-suited for use in catalytic, cutting and electrode materials.
