New advanced calorimetric techniques were developed for more accurate characterization of minerals thus impacting their design, processing, and applications.
TG-DTA and TG-DSC are used to characterize the composition of complex minerals based on the weight changes and phase transformations observed with temperature increase. Additionally, those techniques allow to determine the quantity of the different types of water contained in natural feldspars (absorbed, interlayer, structural). The results for several clays will be discussed.
Knowing the thermodynamics of cancrinite compounds formed during the Bayer process at alumina plants, is critical for selecting the optimal condition for processing and the recycling of the side-products. Some sodalites are part of low activity radioactive waste produced during steam reforming process. Their formation enthalpies are obtained using high temperature solution calorimetry, which allows predicting the dissolution behavior of the waste form and the release of radionuclides thus can be directly applied to the radioactive waste treatment.
