Analysis of Dolomite of Balochistan (Pakistan) by Using X-Ray Fluorescence Spectroscopy (XFS), Simultaneous Differential Thermal Analysis (SDTA), Thermogravimetric Analysis (TGA) and Differential Scanning Calorimetry (DSC)

We deciphered new methods for calculation of thermodynamic parameters from SDTA, TGA & DSC techniques. The stretching of ionic bonds between Mg++ and CO3- and Ca++ and CO3 respectively is conformed on TGA curve at a temperature of 427 degrees K. At 728 K, an ore of dolomite is decomposed due to release of carbon dioxide and carbon monoxide gases and the left over Substance is a mixture of MgO and CaO. The ionic bond breaking occurs at 723 degrees K After this, there is reshuffling of ions due to which MgO and CaO are produced at 816 degrees K and 835 K. respectively. The chemists have to think about the chemical processes to separate MgO, a refractory material, from CaO, after baking dolomite upto about 840 degrees K.
