Kinetic studies for the non-isothermal decomposition of unirradiated and gamma-irradiated silver acetate with 10(3) kGy total gamma-ray doses were carried out in air. The results showed that the decomposition proceeds in one major step in the temperature range of (180-270 degrees C) with the formation of Ag2O as solid residue. The non-isothermal data for un-irradiated and gamma-irradiated silver acetate were analyzed using Flynn-Wall-Ozawa (FWO) and nonlinear Vyazovkin (VYZ) iso-conversional methods. These free models on the investigated data showed a systematic dependence of Ea on. indicating a simple decomposition process. No significant changes in the thermal decomposition behavior of silver acetate were recorded as a result of gamma-irradiation. Calcinations of gamma-irradiated silver acetate (CH3COOAg) at 200 degrees C for 2 hours only led to the formation of pure Ag2O mono-dispersed nanoparticles. X-ray diffraction, FTIR and SEM techniques were employed for characterization of the synthesized nanoparticles.
