Description and Uses

Strontium carbonate has the formula of SrCO₃ and the molecular weight of 147.6326 g/mol. Strontium carbonate occurs in nature as the mineral “strontianite”. The name strontianite comes from a famous location for the mineral, Strontian, Scotland. Strontianite is strontium carbonate as found naturally. It occurs as white or slightly gray orthorhombic crystals with a refractive index of 1.518. The unit-cell parameters are: a = 5.107 ? , b = 8.414 ? , c = 6.029 ? , Z = 4; V = 259.07 ? 3, Den(Calc) = 3.78. The crystal system is orthorhombic with space group Pmcn and point group 2/m, 2/m, 2/m. Strontium carbonate has only one stable form (aragonite-type structure) and temperature of precipitation has no effect on crystal form, unlike that of calcium or magnesium carbonates.

Used for electronic applications. It is used for manufacturing CTV to absorb electrons resulting from the cathode
