Popis:	Kinetic studies on the effect of metal oxide catalysts, (25% w/w) such as Cr2O3, CuO, MnO2, Al2O3 and TiO2, on the thermal decomposition of KBrO3 have been carried out. The kinetic parameters of the catalysed and uncatalysed decompositions were calculated by the Freeman-Carroll, Coats-Redfern and Horowitz-Metzger methods. It has been found that Al2O3 is almost as good a catalyst as any other oxide used unlike in the thermal decomposition of KClO3. In the case of TiO2 there was an increase in the activation energy of decomposition. Of the other oxides Cr2O3 underwent reaction and was converted to dichromate and so the parameters of the reaction were not calculated. The effect of varying amounts of Al2O3 on the thermal decomposition was also studied.
