The thermal analysis and kinetics of oxidation of “NbS2” to Nb2O5 were studied by thermogravimetry. The application of both isothermal and nonisothermal methods was necessary to establish the correct equation

This equation was valid for the reaction of sample reactedα in the interval 0.03 to 0.82–0.91. The apparent activation energy was determined to be 209.59±2.36 kJ mol−1 with the isothermal method and 209.28±1.84 kJ mol−1 with the nonisothermal method (5 deg min−1) over thePo2 range 8.9×10−2 to 2.0×10−1 atm and the temperature range 440 to 515°. The relationship between the rate constantk andPo2 was also determined.
