Jinan three flat Chemical Co., Ltd. was established in 2006, the company is operating in good faith, warm service philosophy specializing in the supply of calcium nitrate, magnesium nitrate, zinc nitrate, magnesium sulfate, calcium sulfate, barium sulfate, ferrous sulfate. In recent years, the chemical industry in Shandong, founded his own strong brand and reputation. Sulfate, a compound represented by the sulfate ions (SO4) and the other metal ions, the electrolyte is, and most soluble in water. Sulfate minerals cation is a metal element (including ammonium) and sulfate salts formed with the compounds. Because sulfur is a variable price elements in nature that it may be in a different valence form different minerals. When it is the highest valence S6 + in combination with four O2- into SO42-, and then with the metal element cations that formed sulfate. In sulfate minerals, and sulfate compounds of metal cations are more than twenty species. That there is a sulfate salt is sulfate. The most important is Ca2 +, Mg2 +, K +, Na +, Ba2 +, Sr2 +, Pb2 +, Fe3 +, Al3 +, Cu2 +. Currently known sulfate mineral species has more than 170 species. Although they account for only 0.1% of the total weight of the earth's crust, but they are gypsum, anhydrite, barite, Glauber's salt, etc. can integrate with a rich industrial significance of deposit. Most sulfate mineral salts is more complex components, and therefore the lower the degree of symmetry of the crystal structure, mainly belonging to monoclinic and orthorhombic. And since most sulfate minerals containing water, so that the physical properties of the most prominent is the low hardness, typically between 2-3.5. In addition, the color is generally colorless and white, the proportion is generally not large, between 2-4. Sulfate mineral formation requires large and low concentrations of oxygen, so the surface part is best suited to form sulfate minerals in place. In this class of minerals, within a generation due to exogenous causes far more important. After which the original raw metal sulfide oxidation from sulfate minerals, accounting for almost half of the species of this class of minerals. In the basin of the chemical deposition of sulfate minerals are potassium, sodium, calcium, magnesium, barium, aluminum hydrous sulphate. As endogenous hydrothermal sulfate minerals, mainly barium, calcium, strontium, and other anhydrous aluminum sulfate, found in epithermal veins or as a low-temperature hydrothermal wall rock alteration product.
