| Summary: | The isothermal decomposition and kinetics of potassium metaperiodate (KIO4) were studied by thermogravimetry as a function of the concentration of dopants. The thermal decomposition of KIO4 proceeds mainly through two stages: an acceleration period up to a = 0.50 and a decay stage. The thermal decomposition data for both doped and untreated KIO4 were found to be best described by the Prout–Tompkins Equation. The a–t data of doped and untreated samples of KIO4 were subjected to isoconversional studies for the determination of the activation energy values. The isoconversional studies of the isothermal decomposition of untreated and doped samples of KIO4 indicated that the thermal decomposition of KIO4 proceeds through a single kinetic model, the Prout–Tompkins model, throughout the entire range of conversion, as opposed to earlier observations.
