Strontium sulfide is the inorganic compound with the formula SrS.

[2][3][4] Strontium sulfide is produced by roasting celestine with coke at 1100–1300 °C.

[5] The sulfate is reduced, leaving the sulfide: About 300,000 tons are processed in this way annually.

[2] Both luminous and nonluminous sulfide phases are known, impurities, defects, and dopants being important.

[6] As expected for a sulfide salt of alkaline earth, the sulfide hydrolyzes readily: For this reason, samples of SrS have an odor of rotten eggs.
