Calcium Sulphate

 Calcium Sulphate is an inorganic compound composed of calcium, sulfur, and oxygen, commonly found in two forms: dihydrate (gypsum, CaSO4·2H2O) and anhydrous (CaSO4). It appears as a white or off-white crystalline powder or granules with low solubility in water. Calcium Sulphate is widely used in construction, agriculture, pharmaceuticals, food industry, and various industrial applications. It acts as a filler, hardening agent, and drying agent due to its physical and chemical properties. The dihydrate form (gypsum) is notable for use in plaster and cement, while the anhydrous form is often used as a drying agent and in refractory materials.
