Abstract
The thermoanalytical data of various silicate glasses are compared. It is pointed out that the higher activation energy values obtained with non-isothermal devitrification techniques are not necessarily indicative of a lower tendency to devitrification. A criterion is proposed for evaluating the relative ease of different vitreous compositions to form glass-ceramic materials.File in questo prodotto:
