Barite Powder

The Barite Powder is insoluble in water, and this property is made use of in testing for the sulfate radical. It is practically insoluble under ordinary conditions in all the usual chemical reagents. Barite is used as a commercial source of barium and many of its compounds. Ground barite is used as a filler in the manufacture of linoleum, oilcloth, paper and textile manufacturing, rubber, and plastics. Finely ground barite is used to make a thixotropic mud for sealing oil wells during drilling. Prime white, a bleached barite, is used as a pigment in white paint but is not as satisfactory as blanc fixe, a chemically precipitated barium sulfate, or lithopone, a mixture of barium sulfate, zinc sulfide, and zinc oxide.
