Gypsum Product - an overview ScienceDirect Topics

Major raw material of gypsum is natural dihydrate gypsum (CaSO 4 2H 2 O) and natural anhydrite (CaSO 4) (also named hard gypsum). Both are named as raw gypsum. Common building gypsum is hemi-hydrate (CaSO 4 1 2 H 2 O), decomposed from dihydrate and anhydrite when heated to 1500-1700 ºC.
