Usage

General Description

Calcium sulfide (Ca(Sx)) is a chemical compound comprised of calcium and sulfur. It is a white solid that is highly reactive and is insoluble in water. Calcium sulfide is primarily used in the production of luminous paints, hydrogen sulfide scrubbing, and in the manufacturing of various types of phosphors and scintillators. It can also be found in some commercial light sources, such as fluorescent lamps and solid-state light-emitting diodes (LEDs). Additionally, it has applications in the field of construction, as it is used as a pigment in the production of asphalt and concrete. Despite its utility, calcium sulfide is a highly toxic substance and must be handled with care to avoid adverse health effects.
