Magnesium Nitride is more commonly referred to as trimagnesium dinitride. It is an inorganic compound and has two atoms of nitrogen and three atoms of magnesium.
Chemical Formula
The chemical formula of magnesium nitride is Mg3N2. It has an anion valency of (3-). Therefore, it is also known as trimagnesium nitrogen(3-).
Structure
The structure of magnesium nitride consists of three cations of magnesium which can be denoted as Mg2+ and two anions of Nitrogen (III) which can be denoted as N3-.
Magnesium nitride is found in nature in the form of the mineral nitromagnesite.
Properties
Physical Properties
Magnesium nitride is greenish yellow in color and exists as a powder in room temperature and normal pressure. It has a molar mass of 100.95 g/mol and has a density of 2.712 g/cm3. It can dissolve in acid and water as well but is slightly soluble in ether and ethanol. The melting point of magnesium nitride is 1500°C and when heated beyond this temperature, it results in decomposition of the powder and forming of a gas of nitrogen.
Chemical Properties
Magnesium nitride is a hard compound and is actually ceramic in nature. Magnesium nitride has high thermal conductivity. It has high corrosion resistance which makes it very useful in the production of other nitride compounds. It also had high wear resistance and temperature resistance. Magnesium nitride is used as a catalyst in the synthesis of borazon.
