Barium sulfate, BaSO 4, is made by reacting barium hydroxide and other barium sources with sulfuric acid and has a long history as a translucent white pigment. Due to the relatively high atomic number (Z = 56) of barium, its compounds absorb X-rays more strongly than compounds derived from lighter nuclei. The active ingredient is barium sulfate and its structural formula is BaSO4. • During the early part of the 20th century, during the Japanese colonization period, hokutolite was found to exist naturally in the Beitou hot-springs area near Taipei City, Taiwan. Hokutolite is a radioactive mineral composed mostly of PbSO4 and BaSO4, but also containing traces of uranium, thorium and radium. Barium sulfate (or sulphate) is the inorganic compound with the chemical formula BaSO4. There are three main steps for writing the net ionic equation for MgSO4 + BaCl2 = BaSO4 + MgCl2 (Magnesium sulfate + Barium chloride). [9] Composites with high weight percentage (70-80%) of barium sulfate perform better than commonly used steel shields. Radium is often removed from this wastewater by co-precipitation with barium or other alkaline earth metals. Barium sulfate is used in soil testing. It is most often used in imaging of the GI tract during what is colloquially known as a "barium meal". You may need to download version 2.0 now from the Chrome Web Store. It occurs as the mineral barite, which is the main commercial source of barium and materials prepared from it. As barium compounds emit a green light when burned, barium salts are often used in green pyrotechnic formulas, although nitrate and chlorate salts are more common. About 80% of the world's barium sulfate production, mostly purified mineral, is consumed as a component of oil well drilling fluid. Baryte is generally white or colorless, and is the main source of the element barium.The baryte group consists of baryte, celestine (strontium sulfate), anglesite (lead sulfate), and anhydrite (calcium sulfate).

Virtually insoluble in water at room temperature, it is mostly used as a component in oil well drilling fluid it occurs naturally as the mineral barite. Barium sulfate is sometimes used (or else PTFE) to coat the interior of integrating spheres due to the high reflectance of the material and near Lambertian characteristics. The anode plates are cast in copper molds, so to avoid the contact of the liquid copper and the solid copper mold, a solution of barium sulfate in water is used as a coating on the mold surface. [11], Although soluble salts of barium are moderately toxic to humans, barium sulfate is nontoxic due to its insolubility. In the laboratory barium sulfate is generated by combining solutions of barium ions and sulfate salts. The structure of the barium sulfate is an orthorhombic lattice. • Its low solubility is exploited in qualitative inorganic analysis as a test for Ba2+ ions as well as for sulfate. With a low surface area, the contact time of the substrate with the catalyst is shorter and thus selectivity is achieved. General Reference Center GOLD. To produce highly pure barium sulfate, the sulfide or chloride is treated with sulfuric acid or sulfate salts: Barium sulfate produced in this way is often called blanc fixe, which is French for "permanent white."
