چکیده    The kinetics of molybdenite oxidation was studied by non-isothermal tga-dta with heating rate 5 °c.miril.the model-fitting kinetic approach applied to tga data .the coats-redfern method used for model fitting. the popular model-fitting gives excellent fit for non-isothermal data in chemically controlled regime. the apparent activation energy was determined to be about 34.2 kcalmol'1 with pre-exponential factor about i08 sec'1 for extent of reaction less than 0.5.
