Factsheet on: What is Gypsum?

From a chemical point of view it is Calcium Sulphate Dihydrate ( CaSO 4.2H 2O) deposited in sedimentary layers on the sea bed. Under high pressure and temperature Gypsum turns into Anhydrite ( CaSO 4). In nature, Gypsum and Anyhdrite occur as beds or nodular masses up to a few metres thick. Gypsum is formed by the hydration of Anhydrite.

Gypsum: an old product with a new use | Integrated Crop ...

Gypsum is calcium sulfate (CaSO 4). Refined gypsum in the anhydrite form (no water) is 29.4 percent calcium (Ca) and 23.5 percent sulfur (S). Usually, gypsum has water associated in the molecular structure (CaSO 4 ·2H2O) and is approximately 23.3 percent Ca and 18.5 percent S (plaster of paris). Gypsum fertilizer usually has other impurities so grades are approximately 22 percent Ca and 17 percent S. …
