Calcium sulfide - Wikipedia

Calcium sulfide is the chemical compound with the formula Ca S.This white material crystallizes in cubes like rock salt. CaS has been studied as a component in a process that would recycle gypsum, a product of flue-gas desulfurization.Like many salts containing sulfide ions, CaS typically has an odour of H 2 S, which results from small amount of this gas formed by hydrolysis of the salt.
