Kinetic analysis of dissociation of smithsonite from a set of non-isothermal data obtained at different heating rates
The isoconversional methods (Friedman and Flynn-Wall-Ozawa) as well as the invariant kinetic parameters method (IKP) were used in order to work the TG data corresponding to the thermal dissociation of smithsonite. As a result we mention a mechanism change at T≈671 K. For T>671 K, which correspond...
