Use

Strontium carbonate occurs in nature as strontianite and can be mined from its deposit. It is, however, usually made from the mineral celestite. Celestite is fused with sodium carbonate at elevated temperatures or boiled with a solution of ammonium carbonate: SrSO4 + Na2CO3 SrCO3 + Na2SO4 SrSO4 + (NH4)2CO3 SrCO3 + 2NH3 + CO2 + H2O Strontium carbonate is insoluble in water. It precipitates from the product mixture in the second reaction. If fused with sodium carbonate, the product mixture is leached with water. Insoluble carbonate separates from the watersoluble sodium sulfate.
