実験手順
When calcium sulfate dihydrate is heated sufficiently, a process called calcining, the water of hydration is driven off and there can be formed either calcium sulfate hemihydrate (CaSC4 ·1/2H2O ) or calcium sulfate anhydrite (CaSO4), depending on the temperature and duration of exposure. The term "calcined gypsum," as used herein, refers to both the hemihydrate and anhydrite forms of calcium sulfate.
