Three kinds of methods for determining the activation energy of crystallization by using differential thermal analysis(DTA) have been derived.The activation energy of crystallization of fluozirconate glass was calculated.The results show by one way analysis of variance that the approximate treatments for the three methods in derivation are rational and there were no significance differences among them.Furthermore the activation energy of crystallization and its relating kinetic parameters have been fitted by the simplex optimization method on the base of the strict theory.The strict result has been compared with those of three approximate methods and literatures.
