The binary compound of nitrogen and an element having less electronegativity, nitride, is formed from the two elements. High electronegativity nitrogen can make a variety of nitrides by combining it with elements that have lower electronegativity. These include covalent and metallic nitrides as well as ionic and covalent nutrides.
These nitrides are formed from alkali and alkaline metal elements and belong to the ionic group. They also have ionic crystals. Li3N is the only element used in ionic nutrides. Li3N is an opaque red solid that belongs to the hexagonal crystal structure. With a density of 1.27g/cm3 it has a melting temperature of 813°C. You can combine it with either liquid or solid. The best lithium coexistence electrolytes are currently in solid form.
Covalent nitrides are formed from group IIIAVIIA element elements. The crystals of these nitrides are made primarily by covalent bonds. They should also be known as nitrogen oxides, nitrogen halides, and compounds that are formed from oxygen and group VIIA element elements. Covalent nitrides that are most commonly used include those made from nitrides belonging to group IIIA, IVA, and BN elements. This structural unit has a similar structure to that of a Diamond’s Tetrahedron, and is therefore also known as class Diamond Nitride. These materials have high hardness, high melting temperature, and excellent chemical stability. Many of these are semiconductors and insulators. They can be found in many applications, including cutting tools, high temperature ceramics, microelectronics devices and luminescent material.
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 to be consistent. They can also vary in composition. 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.
