Calcium Sulfide | CaS | CAS 20548-54-3

Calcium Sulfide (CaS) is a white powder. It is slightly soluble in water and alcohol. It can hydrolyze when it meets water or moisture. It decomposes rapidly when it meets acid and releases hydrogen sulfide gas. It precipitates sulfur when it reacts with chlorine and iodine. It can be doped with different metal ions to be made into phosphorescent materials, which are widely used in luminescent paints, phosphors, and optical devices. HM can supply Calcium Sulfide with a purity of up to 99.9%.

• Chemical formula: CaS
• Appearance: White powder
• Molecular weight: 72.14 g/mol

When calcium sulfide comes into contact with water, it produces hydrogen sulfide gas. Lime sulfur, which contains calcium sulfide, can be created by reacting sulfur dioxide with lime.

Calcium Sulfide (CaS) Applications

1. Phosphorescent Materials: Calcium sulfide doped with metal ions is used to create phosphorescent materials, ideal for applications in luminescent paints, phosphors, and optical devices.

2. Agriculture: Used as a soil conditioner, calcium sulfide helps neutralize acidic soils, improving soil quality for better plant growth.

3. Wastewater Treatment: It removes harmful heavy metals like lead and mercury from wastewater, contributing to environmental purification.

4. Pharmaceutical Industry: Acts as an intermediate or reagent in various chemical processes within pharmaceutical manufacturing.

5. Rubber Industry: Serves as a vulcanization accelerator, enhancing the physical properties of rubber and improving its durability.
