Abstract

A chemical reaction, the hydration of CaSO4.½D2O, was followed in real time in an on-line neutron diffraction experiment at different temperatures. The results of the reactions are presented as diagrams showing the evolution of the intensities of CaSO4.2D2O in real time. The hydration passes through the formation of a gel interphase. The dehydration of CaSO4.2D2O was followed in the same way at temperatures up to 420 K.
