Calcium sulfate - Wikipedia

Calcium sulfate (or calcium sulphate) is the inorganic compound with the formula CaSO 4 and related hydrates. In the form of γ-anhydrite (the anhydrous form), it is used as a desiccant. One particular hydrate is better known as plaster of Paris, and another occurs naturally as the mineral gypsum. It has many uses in industry.

Is Calcium Sulfate Soluble in Water? | Reference

Calcium sulfate is soluble in water in percentages ranging from 0.2 to 0.88 grams per 100 milliliters of water, depending on the anhydrous or hydrated form of the substance. For example, insoluble anhydrite, a dehydrated form of calcium sulfate, dissolves slowly in water and does not absorb moisture from air.
