Thermal decomposition of ferrous oxalate dihydrate was investigated using in situ X-ray diffraction (XRD) analysis and thermogravimetry in static self-generated air. The master plots method along with a statistical procedure was employed to determine the kinetic model and kinetic parameters of the decomposition processes. The dehydration of ferrous oxalate dihydrate conformed to nuclei production and nuclei growth model, and the decomposition of ferrous oxalate conformed to phase boundary reaction. The results showed that the method could estimate the kinetic parameters for nonisothermal decomposition reactions accurately and reliably.
