Abstract

A newly derived crystallization kinetics equation was presented for investigation on crystallization kinetics of 0.7GeSe2–(0.3−x) As2Se3–x CdSe (x=0.1x=0.1, 0.15 and 0.2) glasses under nonisothermal conditions. Activation energy (E) was calculated and compared with several previously reported kinetics equations. The calculated Avrami exponent (n) values were all equal to 3, implying the three-dimensional growth of crystals. Crystallization reaction rate function [k(t )] was introduced in the same equation to estimate glass stability, which was in a good agreement with the conventional indication by ΔT=Tp-TgΔT=Tp-Tg. The compositional dependence of E and k(t)s was discussed. PACS 44.60.+k; 81.10.Aj
