· JVASP-106119· CaMgS2

CaMgS₂ is a mixed-metal sulfide ceramic compound combining calcium and magnesium with sulfur, belonging to the family of chalcogenide ceramics. This material is primarily investigated in research contexts for optical and electronic applications, particularly in infrared-transmitting windows and photonic devices where its sulfide composition offers potential advantages in wavelength transmission beyond conventional oxide ceramics. CaMgS₂ represents an emerging class of materials for specialized optoelectronic applications where tailored bandgap and refractive properties are required, though it remains less established in high-volume industrial production compared to more conventional ceramic alternatives.
