What is gypsum?
Gypsum is a crystalline mineral of hydrated calcium sulphate (chemical formulaCaSO4. 2H2O).
In its natural form, gypsum has a chemical formula of Calcium Sulfate Dihydrate, also known as gypsum with two water molecules (CaSO4.2H2O), with the proportion of water accounting for about 21% of the molecular weight. This material, when heated at a temperature of 150°C, will become Calcium Sulfate Hemihydrate, also known as semi-aqueous gypsum.
In nature, gypsum is found in gypsum mineral deposits. Besides, gypsum can also be generated in chemical plants, or at thermal power plants through the desulfurization reaction of sulfur dioxide.
