چکیده
|
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 1.2×1016 min-1 for region i,and 5.45 kj.mol -1 and 5.23×108 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 67.21×105 min-1,respectively for the suzuki method.
