Barium sulfide precipitate color8/27/2023 The presence of gypsum leads to coagulation and a loss of consistency in the drilling muds. The barite suspensions used in the oil well drilling industry can destabilize when soluble materials such as gypsum are present in the mud. Addition of barium carbonate renders the gypsum insoluble, inhibits the coagulation, and thus permits the mud to retain the desired consistency and dispersion.īarium carbonate is an additive in oil-well drilling muds. In the oil well drilling industry, the barite suspension used as drilling mud can be destabilized by the presence of sol materials such as gypsum. Used in brick and clay products, production of photographic paper. In the brick, tile, earthenware and pottery industries barium carbonate is added to clays to precipitate soluble salts (calcium sulfate and magnesium sulfate) that cause efflorescence.īarium carbonate is insoluble in water and soluble in most acids, with the exception of sulfuric acid.īarium carbonate has a specific gravity of 4.275. To provide a safe means of use, BaO is often used in fritted form. Its use is somewhat controversial since some claim that it can leach from glazes into food and drink. Otherwise it is a common precursor to barium-containing compounds such as ferrites.īarium carbonate is widely used in the ceramics industry as an ingredient in glazes.īarium carbonate acts as a flux, a matting and crystallizing agent and combines with certain colouring oxides to produce unique colours not easily attainable by other means. Pyrolysis of barium carbonate gives barium oxide.īarium carbonate is mainly used to remove sulfate impurities from feedstock of the chlor-alkali process. ![]() In the soda ash process, an aqueous solution of barium sulfide is treated with sodium carbonate:īarium carbonate reacts with acids such as hydrochloric acid to form soluble barium salts, such as barium chloride: ![]() In a commercial sense, it is one of the most important barium compounds.īarium carbonate is made commercially from barium sulfide with by treatment with sodium carbonate at 60 to 70 ☌ (soda ash method) or, more commonly carbon dioxide at 40 to 90 ☌: Like most alkaline earth metal carbonates, it is a white salt that is poorly soluble in water.īarium carbonate occurs as the mineral known as witherite. ![]() Barium carbonate is the inorganic compound with the formula BaCO3.
