Barium sulfate
Barium sulfate (CAS 7727-43-7), with the molecular formula BaSO₄ and a molecular weight of 233.39 g/mol, is a white, crystalline solid. It is widely recognised for its insolubility in water and common solvents. This inorganic salt finds extensive use as a radiocontrast agent in medical imaging and as a filler in various industrial applications due to its high density and inertness.

Medical Imaging
Barium sulfate serves as a crucial radiocontrast agent. When ingested or administered rectally, its high atomic number effectively absorbs X-rays, allowing for clear visualisation of the gastrointestinal tract during diagnostic procedures such as barium meals and enemas.
Industrial Filler
Due to its density, inertness, and opacity to X-rays, barium sulfate is incorporated into plastics, paints, and coatings. It enhances density, provides radiation shielding, and improves sound dampening in automotive components and construction materials.
Chemical Synthesis
As an inorganic salt, barium sulfate can be used in specific chemical syntheses where a source of barium or sulfate is required under conditions where insolubility is advantageous.
Drilling Fluids
In the oil and gas industry, barium sulfate (often referred to as baryte) is used as a weighting agent in drilling fluids to help control formation pressures and prevent blowouts.
