Gypsum is a sedimentary rock and a crystalline mineral. "Gypsum is a soft, white to gray, chalky mineral composed of calcium sulfate and water," says Raymond Anderson of Iowa's Department of Natural Resources. Gypsum's chemical symbol is CaSO4•2H2O.

Beta and Alpha Gypsum. When the hemi-hydrate of gypsum is formed by calcining in kettles at atmospheric pressure, the result is known as Beta gypsum. Alpha gypsum, on the other hand, is made by processing batches of gypsum under elevated pressure. Alpha gypsum has a lower water-carrying capability and is used where high strength is required.


Gypsum Anhydrite vs Gypsum Dihydrate

Anhydrite gypsum is the more concentrated version of calcium sulfate. Gypsum is a fast-release material, anhydrite gypsum a slower-release product which stays in the root zone longer making it available for plant uptake. The true cost of any particular calcium sulfate application may, ultimately, depend on its shipping cost.
