Title

Crystallization Kinetics of Lithia-Silica Glasses: Effect of Composition and Nucleating Agent

Abstract

The kinetics of crystallization of a 25Li2O · 75SiO2 (wt%) glass doped with Pt, Cu, Au, TiO2, and P2O5 were studied using nonisothermal techniques. The activation energy, E, and the frequency factor, v, for the overall crystallization process depended directly on the critical cooling rate for the glass formation, Rc, of these glasses. The crystallization kinetics of several other glasses in the lithia·silica system were also studied as a function of composition, critical cooling rate, and liquidus temperature, Tm. E and v for these glasses were more dependent on the liquidus temperature than on Rc.
