Barite

详情

The barite chemical composition of Ba [SO4], the crystal, the crystal is orthogonal (oblique) sulfate minerals. Usually thick plate-like or columnar crystals, mostly dense block or plate, granular aggregates. The quality of pure colorless and transparent, containing impurities dyed various colors, white streak, vitreous luster, transparent to translucent. Three groups of cleavage completely, the angle is equal to or close to *0 °. Mohs hardness **3.5, specific gravity 4.**4.6. Identification of characteristics: tabular crystals, hardness, the complete cleavage nearly at right angles, the density, the case of hydrochloric acid does not blister, and similar calcite phase difference. Barite is barium sulfate (BaSO4) as a main component of non-metallic minerals, the pure barite were white, shiny, due to the influence of impurity and mixed into the material often has a gray, light red, pale yellow, crystalline very good barite also was transparent crystal. Barite is a mixture.
