Barium Carbonate
BaCO₃ | CAS: 513-77-9 | HS: 28366000
Product Description
Barium Carbonate is one of the most widely used barium compounds globally, serving as the foundational raw material for manufacturing downstream barium salts and as an essential additive in ceramic bodies and specialty glass. In ceramics, it eliminates surface efflorescence on fired tiles by converting soluble calcium sulphate to insoluble barium sulphate — a function no substitute replicates with equal effectiveness. MITCHEM sources from premium ore and processes under ISO 9001:2015 protocols, supplying grades from 98% technical through ultra-high 99.99% purity with full Certificate of Analysis documentation for each shipment.
Applications by Industry
Suppresses efflorescence (white surface scum) on fired ceramic tiles and sanitaryware by reacting with soluble calcium salts; standard addition in wall tile, floor tile, and porcelain body formulations worldwide.
Used as a source of barium oxide in specialty optical glass, CRT glass, and lead-free crystal to increase refractive index and glass density.
Primary feedstock for manufacturing barium nitrate, barium chloride, barium sulphate, barium hydroxide, and other downstream barium chemicals.
Used in barium ferrite (BaFe₁₂O₁₉) permanent magnet production for loudspeakers, motors, and magnetic separators.
Active ingredient source in barium-based rodenticide formulations in regulated markets.
