Barite Market Global Industry Report, 2027

Barite is chemically inert and insoluble. Each grade is used for certain specific applications. Barite is classified based on its purity, i.e. the concentration of barium sulfate present in barite. Accordingly, the specific gravity of barite varies. Barite with specific gravity of 3.9 g/cm3 or less falls under the up to Sp. Gr. 3.9 grade segment.
