Are there any differences in density, refractive index and crystalline structure between barite and precipitated barium sulfate?
Chemically, the two are of the same substance, barium sulfate, but barite is a barium sulfate containing impurities, while barium sulfate is pure. Physically, barite is a white orthorhombic crystal, whereas barium sulfate is a colloidal precipitate
Barite is one of the most important barium minerals, has the proportion of (4.3 - 4.7), low hardness (3 - 3.5) chemically stable, insoluble in water and acid, barite powder is mainly used in oil, chemical industry, paint, packing and other industrial sectors, including 80% - 90% used in petroleum drilling mud weighting agent
The barite has special properties and cheap development cost, is attracting more and more attention. The development of modern industry requires higher purity, whiteness and particle size of barite. Therefore, with the continuous development of science and technology and the deepening of research, more properties of barite will be revealed. Deep processing of barite, such as superfine powder, purification and surface modification, can not only broaden the field of application, but also have better economic benefits, and there is a big demand in domestic and international markets.
