Barium carbonate (BaCO3) is an important alkaline-earth metal material in the production of barium salts, barium ferrite, pigments, ceramics, optical glass, and electric condensers. Additionally, it serves as a precursor to produce superconductors and ceramic materials., preparation of barium standard solution, cement, bricks and in rat poison.
