barium carbonate

Chemistry

A white insoluble compound, BaCO₃; r.d. 4.43. It decomposes on heating to give barium oxide and carbon dioxide:
${BaCO}_{3} (s) \to {BaO (s) + CO}_{2} (g) .$
The compound occurs naturally as the mineral witherite and can be prepared by adding an alkaline solution of a carbonate to a solution of a barium salt. It is used as a raw material for making other barium salts, as a flux for ceramics, and as a raw material in the manufacture of certain types of optical glass.
