Thermal analysis of calcium sulfate dihydrate and supposed

In addition to the calcium sulfate hydrates, two types of anhydrous calcium sulfate exist, hexagonal (y-CaS04) and orthorhombic (8-CaS04) forms [2]. The y form results from the dehydration of the hy­ drates and is regarded as the low-temperature species, although it is apparently metastable and even at room
