Calcium nitride: properties and applications
This compound is made up of calcium and nitrogen. Ca3N2 has the chemical formula. It is a solid crystalline that appears reddish-brown. Calcium nitride dissolves in water and releases ammonia when it comes into contact with the water. Insoluble in dilute acids and decomposes when exposed to alcohol. Calcium nitride (CaN) is made by heating metallic calcium at 450degC with nitrogen.
Is calcium nitride ionic?

If we know the ions that make up an ionic complex, then we can calculate its molecular structure. Calcium ions are also known as Ca2+. The nitride-ion is N3-. In order to balance this charge, three calcium ions are needed, specifically Ca3N2, for every two nitride.
Is calcium nitride a metal?
Calcium nitride (also known as calcium and nitrogen nitride) is a reddish brown crystalline solid. When the calcium burns, it forms Ca3N2 with the oxide CaO. The distilled fibrous metal calcium is heated at 450degC with a pure nitrogen stream. After 3-4 hours, the metal calcium is nitrided to calcium nitride.
Is calcium nitrate salt?
Calcium nitrate (also known as double salt) is made by adding nitric to lime and adding ammonia. It is known as double salt, because it contains two nutrients found in fertilizers that are high in sodium. This is not organic but a modified artificial fertilizer.
How is Calcium Nitride Produced?
When the calcium is burned in the atmosphere, it forms Ca3N2 and the oxide CaO. The distilled fibrous metal calcium is heated at 450degC with a purified nitrogen stream, and after 3-4 hours the metallic calcium becomes calcium nitride.
According to the temperature of preparation, the calcium nitride obtained is either black (at 350degC), milky white (between 350 and 1150degC) or golden yellow (above 1150degC). Calcium nitride can be easily identified because it can react to moisture or water, producing calcium and ammonia.
Calcium Nitride: Application
Ca3N2 is used to get reactive nitride and calcium (desiccant), which can be obtained by heating calcium nitride above 350degC.
