Description and Uses
Calcium nitride has the formula of Ca3N2 and the
molecular weight of grams per mole. It can be prepared
by the reactionofCametal inapure streamof nitrogen gas:
3Ca + 2N2 ? Ca3N2
A second method is the decomposition of an amide:
3Ca(NH2)2 + heat ? Ca3N2 + 4NH3
This must be accomplished in an inert atmosphere
(not nitrogen gas). It is a reddish-brown powder. Its
CAS number is 12013-82-0 and its density is 2.76 g/
cm3. It melts at 1195 °C (2183 F).α-Calcium nitride
is the commonly encountered form. It has an antibixbyite
structure similar to Mn2O3, except that the
positions of the ions are reversed: calcium (Ca2+)
ions take the oxide (O2-) positions and nitride ions
(N3-) that of the manganese (Mn3+). If Ca metal is
burned in air, it forms the oxide, CaO, and the
nitride, Ca3N2. The latter reacts with atmospheric
moisture to produce the hydroxide of calcium and
ammonia:
Ca3N2 + 6H2O ? 3Ca(OH)2 + 2NH3
Calcium nitride is used as a nitride source in metathesis reactions to produce complex nitrides as well as SiAlON-related optical materials.
