Calcium sulfate CAS 7778-18-9(anhydrous) 10101-41-4(dihydrate)
CALCIUM SULFATE CAS 7778-18-9(anhydrous) 10101-41-4(dihydrate)
Calcium sulfate (anhydrous and dihydrate) is a versatile, low-cost inorganic salt with widespread applications across construction, agriculture, food, pharmaceuticals, and industry. Its key advantages include chemical stability, biocompatibility, environmental friendliness (via byproduct recycling), and dual nutrient supply (Ca/S) for agriculture. The dihydrate (gypsum) is primarily used in construction and soil amendment, while the anhydrous form excels in high-purity applications (food, pharmaceuticals) and industrial fillers. As a staple product in global supply chains, calcium sulfate continues to gain traction due to its sustainability and multi-industry utility.
