Kinetic parameters of tincalconite during thermal decomposition were explored with TGA data. Coats-Redfern and Suzuki methods were implemented for the kinetics analysis. Decomposition kinetics of tincalconite occurred in two steps and both suitably fit a first-order kinetic model. Activation energy and frequency factor were observed as 149.17 kJ.mol−1 and 1.2x1016 min−1 for region I, and 5.45 kJ.mol-1 and 5.23x108 min-1 for region II, respectively with the Coats-Redfern method. Activation energy and frequency factor were observed as 60.95 kJ.mol-1 and 67.21x105 min-1, respectively for the Suzuki method.
