Description and Uses

Barium carbonate has the molecular formula of BaCO3 and the molecular weight of 197.3359 g/mol. Its CAS number is 513-77-9. Barium 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.

Rat poison; in ceramics, paints, enamels, marble substitutes, rubber; manufacture of paper, barium salts, electrodes, optical glasses; as an analytical reagent.
