overview
Calcium sulfate is also known as raw gypsum, hard raw paste, Muriacite, anhydrous gypsum. Colorless orthorhombic crystals (β type) or monoclinic crystals (α type). The relative molecular weight is 136.14. The relative density is 2.960. Melting point 1193 °C (from β type to α type), 1450 °C (α type, and decomposition). Slightly soluble in water (0.209 at 20 °C), soluble in acid, ammonium salt, sodium thiosulfate, sodium chloride solution and glycerol. Even if water is added, it can no longer become calcium sulfate dihydrate. If the natural gypsum ore is completely dehydrated below 300 °C, soluble anhydrous stone Chemicalbook paste dissolved in water can be generated; If natural gypsum is heated above 600°C, insoluble anhydrous gypsum is formed. Anhydrous calcium sulfate or cooked gypsum is mixed with an appropriate amount of water, that is, it slowly solidifies. It is used as a blocker, adhesive, moisture absorber, polishing powder, paper filler, gas desiccant, gypsum bandage, and handicrafts. The raw material for making cement from gypsum can adjust the cement setting time. coagulant used in food for tofu making; yeast feed; dough conditioner; Chelating agents. There are natural gypsum mines, and the by-products of the phosphate industry contain calcium sulfate, and the ammonium sulfate solution reacts with the calcium chloride solution, suction filtration, washing and precipitation, and can be made into pure products.
