· SrS

Strontium sulfide (SrS) is an inorganic ceramic compound belonging to the rock salt family of binary ionic ceramics. It is primarily investigated in research contexts for optoelectronic and photonic applications, particularly in thin-film form for infrared windows, scintillation detectors, and phosphor applications where its wide bandgap and optical properties are advantageous. SrS is less commonly encountered in high-volume industrial production compared to more established ceramics like alumina or yttria, making it a specialized material for laboratories and advanced technology development rather than conventional structural engineering.
