Strontium Carbonate
• Formula: SrCO3
• Molecular weight: 197.35
• Appearance: White powder or grain
• Nature: White powder or grain, hard to dissolve in water, slightly soluble in ammonia and ammonium carbonate, nonsoluble in alcohol. It is kind of rhombic system matter, generate carbon dioxide by reacting with acid.
• Use: As a basic ingredient of strontium salt. It mainly be used for producing CRT, refining of sugar and producing electromagnet ferrite and strontium ferrite, it is also can be used for producing fire works, paper, medicine, fluorescence glass and analysis agent etc.
• Quality standard: GB/T 1614-1999
