Description
BARIUM SULFATE
CAS Number: 7727-43-7
Description:
Barium sulfate is an inorganic compound with the chemical formula BaSO₄. It is a white, odorless, and crystalline solid that is insoluble in water. Barium sulfate occurs naturally as the mineral barite, and it is primarily produced synthetically for various industrial applications. Due to its high density and low solubility, it is widely used in industries such as oil and gas, coatings, and plastics. It also has applications in the manufacture of specialty glass and ceramics.
Properties:
- Molecular Formula: BaSO₄
- Molar Mass: 233.39 g/mol
- Appearance: White, crystalline solid
- Solubility: Insoluble in water, alcohol, and acetone
- Melting Point: 1580°C
- Density: 4.5 g/cm³
Applications:
- Oil and Gas Drilling: Barium sulfate is a key component of drilling fluids, where it is used to control the pressure within the wellbore during the drilling process. It helps prevent blowouts and stabilizes the well.
- Paints and Coatings: Barium sulfate is used as a white pigment in paints and coatings, providing opacity and improving the brightness and finish of the products.
- Plastics and Rubber: It is used as a filler in plastics and rubber materials to improve their properties, including their rigidity, durability, and overall strength.
- Specialty Glass and Ceramics: Barium sulfate is added to specialty glass and ceramics to improve their physical properties, such as strength and resistance to thermal shock.
- Pigment Production: It serves as a pigment in the production of certain dyes and pigments, particularly those used in manufacturing ceramics, glass, and paints.
