(inorganic chemistry)

CaS In pure form, white cubic crystals, slightly soluble in water; used as a base for luminescent materials. Also known as hepar calcies; sulfurated lime.

Calcium Sulfide

CaS, a salt; colorless crystals with a density of 2.58 g/cm³ and a melting point of 2000°C. Calcium sulfide is obtained by the calcination of CaSO₄ with charcoal. It is used in the preparation of luminophors and in the tanning industry for the removal of hair from hides. Calcium hydrosulfide Ca(SH) ₂ is used in the production of synthetic fibers.
