Calcium Nitride Formula

How is Calcium Nitride Prepared

It can be synthesized when calcium is heated at an elevated temperature in the presence of air, which is represented by the following direct reaction of the elements [2]:

3Ca N2 → Ca3N2

The calcium nitride formed can be easily identified, as it reacts with moisture or water to produce calcium hydroxide and ammonia [2]:

Ca3N2 6H2O → 3Ca(OH)2 2NH3

Calcium Nitride Chemical Structure

Uses

  • Ca3N2 can be used for obtaining reactive nitride ions [5].
  • Calcium hydride (a desiccant) can be produced by heating calcium nitride with hydrogen at temperatures above 350 °C [2].

Is it Toxic

Repeated contact or overexposure to Ca3N2 has been linked to eye damage and skin burns [6]. It is a flammable solid and should be kept away from sparks, heat, open flames, and water, because of possible dangerous reactions [6].
