Abstract
Isothermal and non-isothermal kinetics of gehlenite glass devitrification have been studied. A Johnson—Mehl—Avrami rate equation was assumed. The values of kinetic parameters obtained from XRD patterns and DTA curves are in a good agreement. The crystallization process is thought to proceed by a rod-like growth controlled by diffusion from a fixed number of nuclei.
