Strontium Sulfide

Strontium sulfide is a chemical compound composed of strontium (Sr) and sulfur (S). It is classified as a chemical in the supply class Chemicals and belongs to the supply group Chemicals and Chemical Products.

Strontium sulfide is typically found as a white or yellowish powder. It has a chemical formula of SrS and a molecular weight of 119.63 g/mol. It is insoluble in water but can dissolve in acids.

This compound is commonly used in various applications, including:

1. Pyrotechnics: Strontium sulfide is used in fireworks and flares to produce a red color. When heated, it emits a bright red light.

2. Luminescent Materials: It is also used in the production of luminescent materials, such as glow-in-the-dark paints and coatings. Strontium sulfide can absorb and store energy, then release it as visible light over time.

3. Photocatalysis: Strontium sulfide has photocatalytic properties, meaning it can accelerate chemical reactions when exposed to light. This property makes it useful in applications like water purification and air pollution control.

4. Electronics: Strontium sulfide is used in the production of cathode ray tubes (CRTs) for televisions and computer monitors. It helps enhance the brightness and color quality of the display.

5. Chemical Synthesis: It can be used as a precursor in the synthesis of other strontium compounds or as a sulfur source in various chemical reactions.

It is important to handle strontium sulfide with care, as it can be toxic if ingested or inhaled. Proper safety precautions, such as wearing protective gloves and a mask, should be followed when working with this compound.
