Crystallization of Calcia-Gallia-Silica Glasses
The critical cooling rate, Rc, for glass formation and the kinetics of crystallization of the compositions 18.4CaO-(81.6 - X)Ga2O3-XSiO2 (in wt%), with X=3, 6, 9, and 13.8, were studied by using a thermal image furnace. Crystallization was studied nonisothermally and the data were analyzed by using the Avrami equation. The Rc and activation energy for crystallization both decrease with increasing silica content. The results obtained by the present technique agree with those obtained from DTA measurements.
