Strontium nitride is an inorganic chemical compound of strontium from the group of nitrides .

Extraction and presentation

Strontium nitride can be obtained by a two-stage azotization of strontium with nitrogen at different temperatures .

{\ displaystyle {\ ce {3Sr + N2 -> Sr3N2}}}

It is also formed when strontium is burned in air.

properties

Strontium nitride is a black solid that reacts violently with water to form strontium hydroxide and ammonia . In addition to strontium nitride, there is also the subnitride Sr ₂ N.
