Calcium nitride is an inorganic chemical compound of calcium selected from the group of nitrides.

Production and representation

Calcium nitride can ( among other things, its combustion in air) are obtained with nitrogen by reaction of calcium.

It can also be obtained by decomposition of calcium amide.

Properties

Calcium nitride, depending on the representation of temperature before and black to golden yellow or mixed colors. α - calcium nitride (C- type sesquioxide or anti - bixbyite structure, space group Ia3 with the lattice parameters a = 10.40 Å) passes over at 700 ° C in β - calcium nitride.

With water decomposition takes place to calcium hydroxide and ammonia.
