Strontium Carbonate
Chemical Name: Strontium Carbonate
Synonyms: Strontium Carbonate Granular,
CAS No.: 1633-05-2, 1633-55-2
Relative molecular mass: 147.63
Molecular Formula: SrCO3
White powder. Relative density: 3.70. Melting point 1497℃(under CO2 atmosphere). Decompose to emit carbon dioxide when heats up to 1340℃. Difficult to dissolve in water, slightly soluble in ammonia and ammonium carbonate. Does not dissolve in alcohol, easily dissolve in ammonium chloride and ammonium nitrate. Change into strontium chloride when boil with dioxide. Emit carbon dioxide when react with acid. Dissolve to become strontium hydrogen carbonate in water containing carbon dioxide. Meet hydrogen sulfide to create sulfur when suspend in water.

Application:
Basic material of producing strontium salt. Glass made by strontium carbonate has strong power to absorb X radial. Widely used in producing the cathodate ray tube of color television. Also used in electromagnet, oxygen of strontium and iron, can crank out mini television and be applied for adding electrocyte of metal zinc, potassium salt, paint manufacturing and so on.
Packing:
25kgs in PE/PPbag or metal drum, 500/1000kgs in PP bag, 200kgs in metal drum, or per client's requirement.
