| Abstract: | Thermal decomposition of nickel fluorenone-semicarbazone has been studied by TG. Thermoanalytical data (TG and DTG) of the chelate are presented. Mass loss considerations at the main decomposition stages indicate conversion of the complex to oxide. Mathematical analysis of TG data shows that first order kinetics is applicable for the first stage and second order to the second stage. Kinetic parameters (energy and entropy of activation and preexponential factor) are reported.
