formula for calcium nitride

The formula of calcium nitride is Ca3N2 with the appearance of a reddish-brown crystalline solid. It is a chemical reagent, used in phosphor production and other applications. It is an inorganic compound that has a variety of isomorphous forms, including a-calcium nitride.

Producing Calcium Nitride

A calcium nitride preparation involves heating fine fibrous metal calcium (purified by distillation) to 450 degC in pure nitrogen gas flow for 3 4 h, which causes the crystal transformation of the calcium metal (hexagonal crystal Ca -body-centered cubic Ca). After this, the lattice structure of the metal is loose, and a nitriding reaction occurs very quickly, producing a large amount of calcium nitride.

It is easy to identify a-calcium nitride because it reacts with water to produce calcium hydroxide and ammonia, which are soluble in dilute acid and decompose in anhydrous alcohol. It is also reactive with hydrogen to produce calcium hydride, which is a desiccant.

It is a highly flammable solid that should be kept away from sparks, heat, open flames, and water, because of the possible dangerous reactions it can cause. It is best to use a protective covering or store in a dry place. It can be ingested, but it is recommended to take only small doses of 500 milligrams or less. It is not toxic to humans, but it can cause eye damage and skin burns if repeated contact or overexposure occurs. It is also known to increase blood pressure and heart rate, so it should be avoided by individuals with cardiovascular disease or other risk factors.
