Barium Carbonate CAS:513-77-9

Barium carbonate (BaCO3) is a common inorganic barium salt compound that is insoluble in water and organic solvents and can react with acids to release carbon dioxide.

It is widely used in rodenticides, manufacturing cement, electroceramic materials, glazes, bricks, frits, and enamels. It is used as a coating for welding electrodes and as a purifier in the glassmaking process to ensure uniformity during the purification of glass melts and caustic soda brine. The product is also used as a source for the manufacture of other barium chemicals such as chlorides, peroxides, and nitrates.

In addition, BaCO3/tin dioxide nanoparticles also have photocatalytic activity and can be used for the degradation of crystal violet dye, which is a relatively stable process. When the dosage of BaCO3/tin dioxide nanoparticles was 10 mg/10 mL crystal violet dye solution and the UV-visible light irradiation time was 8 h, the crystal violet degradation rate reached 92.1%; when the dosage of BaCO3/tin dioxide nanoparticles was increased to 20 mg/10 mL crystal violet dye solution, the crystal violet degradation rate increased to 96.1%; the active species capture photocatalytic experiment showed that holes, hydroxyl radicals and superoxide ion radicals were the main active species.
