Barium carbonate is prepared from barium sulfide for its commercial purposes. Barium sulfide is treated with sodium carbonate at 60°C to 70°C, this is called the soda ash method. The more commonly used method is the carbonation method, where barium sulfide is treated with carbon dioxide at 40°C to 90°C instead of sodium carbonate.

The process begins by passing the carbon dioxide through a barium sulfide solution, which produces a barium carbonate slurry. The content is further processed and undergoes desulphurization and vacuum filtration. The chemical compound is then dried at around 300 degrees C to finally obtain the resultant product, i.e., Barium carbonate.
