Description

Barium Sulfide (BaS), Black is an important inorganic chemical compound primarily used as a precursor in the production of other barium compounds and as a depilatory agent. Its commercial significance lies in its role as a key intermediate for manufacturing barium salts, pigments, and specialty chemicals across various heavy industries. This product is essential for suppliers and manufacturers in sectors such as chemical synthesis, pigment production, and specific metallurgical processes.

Application

• Chemical Synthesis: A primary raw material for the production of other barium compounds like barium carbonate, barium chloride, and barium nitrate.
• Pigment Industry: Used in the manufacture of lithopone, a white pigment consisting of a mixture of barium sulfate and zinc sulfide.
• Depilatory Agent: Employed in leather processing for unhairing hides and in some cosmetic depilatory creams.
• Luminescent Materials: Acts as a precursor in the production of certain phosphors and electroluminescent materials.
• Metallurgy: Used in some metal heat treatment processes and as a source of barium in alloy production.
• Analytical Chemistry: Utilized in qualitative inorganic analysis for the detection of certain metal ions.
• Vulcanization Accelerator: Serves as an ingredient in the vulcanization of certain synthetic rubbers.
