ANS012 Thermal characterization of calcium oxalate

The characterization of minerals involves the analysis of their composition. For instance, calcium oxalate is a calcium salt of oxalate whose monohydrate form occurs naturally as the mineral whewellite. TGA allows for the characterization of minerals through their mass variation during heating and when different reactions like dehydration, dehydroxylation, or thermal dissociation occur. STA provides additional information about the thermal behavior of the mineral, like the endothermic or exothermic character of the detected reaction.
