Scope

This document specifies a method for determining the activation energy using the Oz awa-Fri edman plot. This document also specifies the method for verifying the reaction kinetic master curve by thermogravimetric method. The Oz awa-Friedman plot (under a certain mass loss, the logarithm of the mass loss rate is used to plot the inverse of the temperature under the mass loss) is a differential method that can be applied to the thermal analysis of the program of arbitrary temperature changes, Such as constant temperature, constant heating rate, sample size control thermal analysis, temperature step and repeated temperature scan.
