摘要：

Kinetics analysis for non-isothermal decomposition of un-irradiated and pre-gamma-irradiated anhydrous indium acetate was studied in the temperature range (298-1273 K) in static air using dynamics thermogravimetric techniques. The data were analyzed using various solid state reaction models. Integral method using Coats-Redfern equation was applied in dynamic data analysis. The results showed that the kinetic of non-isothermal (dynamic) decomposition was controlled by phase boundary process. The activation energies for un-irradiated and pre-gamma-irradiated anhydrous indium acetate were calculated and evaluated. (C) 2010 King Saud University. All rights reserved.
