Kinetic parameters of the thermal decomposition of trimethylindium by DSC

Abstract DSC curves of trimethylindium were recorded at different heating rates and crucible loading densities. The two dominating exothermic bands were kinetically analysed by fitting a two-step reaction model of first-order to the deconvoluted DSC data. The kinetic parameters, calculated at low loading densities, are log z 1  = 18.3 ± 0.2 s −1 , E 1  = 215.4 ± 0.8 kJ/mol and log z 2  = 9.3 ±0.2 s −1 , E 2  = 139.2 ± 0.8 kJ/mol.
