What is Barite Powder? Barite, also known as barytes, is a mineral composed of barium sulfate (BaSO4). It occurs in various forms, including massive, tabular, and rhomboidal crystals, and is commonly found in sedimentary rocks. The mineral's name is derived from the Greek word "barys," meaning "heavy," owing to its exceptional density.
