Abstract

The effect of the addition of Ag2O on the mechanism of non-isothermal devitrification of Li2O · 2 SiO2 glass has been studied by differential thermal analysis. In both bulk and powdered samples, the presence of heterogeneous nuclei lowers the crystallization temperatures but not the value of the crystal growth activation energy. The influence of the catalyst on the crystallization mechanism is not affected by a pre vious heat treatment at the temperature of the maximum nucleation rate.
