摘要
A simple method of determination of kinetic parameters by analysis of DTA(t) function was developed for the case of systems undergoing transitions without mass change and when kinetic equation describing transition rate is known. The presented method also permits the determination of transition rate d alpha /dt (or alpha (t)) when the kinetic equation of transition is unknown. The developed method was tested using DTA data of crystallization of 2CaO . Al2O3.1.95SiO(2) glass pure and doped with Cr3+ and Nd3+.
