Mechanism and kinetics from non-isothermal TG traces
TL;DR: In this paper, the authors presented a linear plot of the TG trace corresponding to a heterogeneous process which proceeds with a constant increase of the temperature, where α is the fraction decomposed, function g(α) is given by the rate controlling process and function p( x ) depends on its activation energy.
