Barium carbonate (BaCO₃) is an inorganic ceramic compound widely used as a raw material and functional additive in ceramics, glass, and chemical manufacturing. It serves as a source of barium oxide in glazes, enamels, and glass formulations, where it improves melt fluidity and thermal stability, and is also employed in electronics, pigment production, and as a precursor for other barium compounds. Engineers select BaCO₃ for applications requiring high-temperature stability, optical transparency enhancement, or controlled barium source delivery, though its use requires careful handling in applications where solubility or toxicity considerations apply.
