Kinetics of the Heterogeneous Solid State Process
Heterogeneous solid state processes do not involve the physical parameters that characterize the state of reaction system homogeneously during the reaction. A close examination of the DSC plots (refer Fig. 4.1) of the samples at different heating rate reveals the asymmetric nature, which implies the occurrence of intermediate reactions during the process. Here, it is felt that identification of these intermediate reactions and the kinetic laws, which remain operative, will help one to cast a deeper insight into the evolution of iron oxide nanoparticles from the organic precursor.
