Calcium nitride - Wikipedia

Calcium nitride is formed along with the oxide, CaO, when calcium burns in air. It can be produced by direct reaction of the elements: 3 Ca + N 2 → Ca 3 N 2. It reacts with water or even the moisture in air to give ammonia and calcium hydroxide: Ca 3 N 2 + 6 H 2 O → 3 Ca(OH) 2 + 2 NH 3
