Description: Barium carbonate is produced through precipitation from barite ore or carbonation of barium sulfide, serving as a key material in ceramic glazes (produces insoluble BaSiO₃ at high temperatures), specialty glass (improves refractive index), and rodenticides. Its low solubility (0.002g/100mL at 20°C) enables controlled barium ion release, while thermal decomposition (>1300°C) yields BaO for electronic ceramics.
