Description

Barium Carbonate is a high-purity, white, odorless powder essential for manufacturing processes requiring a stable and reliable source of barium. This inorganic compound is valued for its role in producing specialty glasses, ceramics, and other barium salts with consistent quality. It is a critical raw material for manufacturers in the ceramics, glass, brick, tile, and chemical synthesis industries seeking to enhance product durability and performance.

Application

• Brick, Tile, and Ceramic Manufacturing: Acts as a flux to lower melting temperatures and enhance the durability and finish of clay products.
• Specialty Glass Production: Used in optical glass, television and computer monitor glass (CRT), and glass for radiation shielding to increase refractive index and brilliance.
• Chemical Synthesis: Serves as a key precursor for producing other barium compounds, such as barium titanate for electronics and barium chloride for water treatment.
• Electronics Industry: A vital component in the manufacture of dielectric ceramics for multilayer capacitors (MLCCs) and positive temperature coefficient (PTC) thermistors.
• Rat Poison and Insecticide Formulation: Employed as an active ingredient in certain rodenticide and pesticide products.
• Cement and Construction: Added in small quantities to cement to act as a setting retardant.
• Ferrite Magnet Production: Used in the synthesis of hard ferrite magnets for motors and speakers.
