Abstract
The devitrification on reheating of the BIGaZYbTM glasses (M : Li, Na, K) was characterized using differential scanning calorimeter. Isother mal and non-isothermal methods allowed the determination of the Avrami 's parameters, n situated between 2 - 4 and the apparent activation en ergy E varying from 30 to 55 kcal/mol. These last values explain the e xcellent stability of these glasses against crystallization.
