The thermal characterization of the scrubber sludge and the mineral gypsum samples was carried out using DSC and DTA techniques. In DSC experiments, the samples were subjected to heating in N2 atmosphere at temperatures 40°C < T < 450°C using a well calibrated [9,10] Perkin-Elmer DSC 7 system. … Fetch Document

The ‘loss on ignition’ (L.O.I.) values may be important for laboratories using borate fusion as a sample preparation method (1) for multielement X-ray fluorescence analysis of gypsum (2, 3). Tests carried out on gypsum by thermal analysis (DTA-TGA) confirmed that the final product of gypsum … Return Doc

Calcite – Wikipedia, The Free Encyclopedia
Calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (Ca C O 3). The other polymorphs are the minerals aragonite and vaterite. Aragonite will change to calcite at 380-470°C, and vaterite is even less stable. Calcite crystals are trigonal-rhombohedral, though actual … Read Article
