摘要
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 1.2x10(16) min(-1) for region I, and 5.45 kJ.mol(-1) and 5.23x10(8) 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 67.21x10(5) min(-1), respectively for the Suzuki method.
