bariumsulfattia

Bariumsulfattia is the Swedish name for barium sulfate. Barium sulfate is an inorganic compound with the chemical formula BaSO4. It is a white, crystalline solid that is insoluble in water and most organic solvents. Its insolubility is a key property that makes it useful in various applications.

One of the most well-known uses of barium sulfate is in medical imaging, specifically as a radiocontrast agent. When a patient swallows or is given an enema containing barium sulfate, it coats the lining of the digestive tract. X-rays can then pass through the soft tissues of the body but are absorbed by the denser barium, creating a clear outline of the esophagus, stomach, and intestines on the resulting image. This helps doctors diagnose conditions such as ulcers, blockages, or tumors.

Beyond its medical applications, barium sulfate is also used in industrial settings. It serves as a filler in plastics, paints, and rubber, adding density and opacity. In the oil and gas industry, it is a primary component of drilling fluids, helping to control pressure and prevent blowouts. Its inertness and resistance to chemical attack also make it suitable for use in certain types of brake pads and as a component in some types of glass. While it is a compound of a heavy metal, barium sulfate itself is considered relatively non-toxic due to its extreme insolubility, meaning it passes through the body without being absorbed.
