摘要：

The decomposition of CaSO4.2H2O under the conditions of TA consists of two consecutive reactions, firstly CaSO4.0.5H2O then CaSO4III being formed. The dehydration is a two-step process even when the TA curves illustrate that it is a one-step reaction. The water loss process takes place with a significant delay owing to protracted nucleus formation on the one hand and to interface processes occurring within the grains and to the reduction in the degree of dispersion caused by the sintering of the grains on the other hand.
