  journal={Thermochimica Acta},
Abstract The thermal analysis and kinetics of oxidation of monoclinic “Cr 3 S 4 ”, trigonal “Cr 2 S 3 ” and rhombohedral “Cr 2 S 3 ” phases were studied by using both thermogravimetry and high temperature X-ray diffraction technique. The oxidation reactions of Cr x S (x = 0.677 ~ 0.751) were as follows: low temperature range (450° ~ 500°C); high temperature range (500° ~ 645°C); Both the reactions were dependent on temperature, partial pressure of oxygen and phases of chromium sulfides… Expand
