It is used in the production of phosphors for cathode ray tubes (CRTs) and other display technologies.
Barium sulphide can be used in scintillation counters, which are devices that detect and measure ionizing radiation.
It serves as a precursor for the synthesis of other barium compounds, such as barium carbonate, barium hydroxide, and barium titanate.
Barium sulphide can be used as a pigment in ceramics and glass.
It is employed as a reducing agent in various chemical reactions.
Please note that specific technical data sheets for barium sulphide may vary depending on the manufacturer and grade of the compound. If you require detailed technical information or safety data sheets, I would recommend consulting reliable chemical suppliers or manufacturers who can provide you with the specific information you need.
