Product introduction
Calcium sulfate is an inorganic compound with the chemical formula of CaSO4, CAS No. 7778-18-9.
Calcium sulfate is divided into industrial grade, food grade and feed grade according to its use; According to the content, it can be divided into anhydrous calcium sulfate and dihydrate calcium sulfate, both of which can reach more than 98%. Among them, anhydrous calcium sulfate is also called gypsum, which is produced by calcining ores at high temperature, and dihydrate calcium sulfate is also called gypsum, which is grinded or chemically synthesized. We also have calcium sulfate as a by-product of lactic acid, calcium sulfate as a by-product of desulfurization, and calcium sulfate as a by-product of phosphate fertilizer plants. The specifications are complete. You can call us directly for specific product specifications and contents.
Calcium sulfate is generally in powder form, and the mesh size can be 200 mesh, 400 mesh, 1250 mesh. Calcium sulfate dihydrate also has block shape.
