01 /Applications

Ceramic and Glass Industries

Barium carbonate is widely employed as a fluxing agent in ceramic glazes, reducing their melting point and improving the finish. In glass manufacturing, it enhances the refractive index and lustre of the glass.

Chemical Synthesis

It serves as a precursor for the synthesis of other barium compounds, such as barium chloride and barium nitrate. These compounds have numerous downstream applications in various chemical processes.

Pest Control

Due to its toxicity, barium carbonate has historically been used as an ingredient in rodenticides. Its application in this area requires careful handling and adherence to regulations.

Specialty Applications

It is used in the production of specialty bricks, tiles, and enamels, contributing to their colour and durability. It also finds niche applications in pyrotechnics and electronics.
