cze Combined Kinetic Analysis for Crystallization Kinetics of Non-crystalline Solids A new method of kinetic analysis that allows the combined analysis of data obtained under different experimental conditions, i. e. heating pathway, is presented for the crystallization of non-crystalline solids. The method consists of a two-stage procedure. Firstly, an optimization procedure is applied for the determination of the Johnson, Mehl and Avrami (JMA). This optimization procedure is based on the linearization of the rate equation throw a logarithmic transformation; where the correlation coefficient function is the objective function, and the JMA order is the adjustable parameter. The JMA order obtained from this optimization procedure allows one to determine in a second stage the other kinetic parameters. crystallization kinetics of non-crystalline solids
