Barium Sulfate Formula

Barium sulfate is an inorganic compound with a chemical formula BaSO4. It is a white crystalline, odourless solid that has many applications including medical uses. Barium sulfate occurs naturally as the mineral barite. Barium sulfate is obtained from barite after mining and processing. The processing of the impure barite requires heating it with coke to produce the water-soluble barium sulfide, which is then segregated from the impurities and is made to react with sulfuric acid to give barium sulfate product. In this short piece of article, let us learn more about the barium sulfate formula, its properties and chemical structure along with its uses.
