The inorganic compound Barium Sulfate, often known as Baritop, Barosperse, and Barite has the chemical formula BaSO4. It is a crystalline white substance that is odorless and water-insoluble. It is found in the mineral Barite, which is the most common commercial source of Barium and barium-based products. Its principal applications take advantage of its white opaque look and great density. About 80% of the world's Barium Sulfate production end up as an oil-well drilling fluid. It raises the density of the drilling fluid leading to an increase in the hydrostatic pressure in the well and lowers the risk of a blowout. A USP Grade chemical is the one that conforms to the criteria of the United States Pharmacopeia (USP). A substance that has received the USP Grade certification can be used in food, drug, or medical applications. Because of its great purity, our Barium Sulfate, USP Grade is a USP Grade chemical.

Questions & Answers

  • can barium sulfate be used in plant growth. and where in mn can it be purchased and size comparative (equil to)

    Barium sulfate (BaSO4) can be used in soil to decrease the availability of barium (Ba) to plants. Barium is a non-essential element that can be toxic to plants and cause growth issues and homeostasis disturbances. When sulfur (S) is present in the soil, it can cause Ba to precipitate as BaSO4, a compound with very low solubility. This can reduce the amount of Ba available to plants and decrease its toxicity.
