Barium sulfate in nature mainly in the form of barite ore formula BaSO4.
The crystal structure of the barite was The large tubular crystal together sometimes may be formed roses shape or bifurcated ingot, this is called crested barite.
Pure barite is colorless and transparent, generally white or pale yellow, with a vitreous luster, due to the influence of impurities and mixed material often has gray, light pink, pale yellow, crystalline quite good barite can also be a transparent crystals appear.
The physical and chemical properties of barite Mohs hardness of 3 to 3.5, specific gravity of 4.3 to 4.7, with a significant low hardness, brittle characteristics.
Chemically stable, can hardly contain water, acid and alkali resistant, non-toxic, non-magnetic characteristics of the absorption of X-rays and gamma rays.
Barite powder can be used as a white pigment, chemical, paper, textile and other industries can also be used as a filler in glass production, it can act as a flux and to increase the brightness of the glass
