Abstract

Infrared emission spectroscopy has been used to study the phase transformations of gypsum, thenardite, glauberite, and anhydrite between the temperatures of 50 and 1400°C. It is shown that emission spectroscopy can be used to monitor these changes <i>in situ</i> and that metastable forms and reversible transformations are easily detected.
