Abstract: -
We have studied the phase separation behavior by spiondal decomposition of two sodium borosilicate glasses of the following composition (weight%) 8Na2O-32B2O3-60SiO2 (glassA) and 8Na2O-27 B2O3-65SiO2 (glass B). From photographs of glass samples obtained with a scanning electron microscope, we have determined the growth of the mean size r of the microstructures of the east phase as a function of the time of the thermal treatment (0-100 h) and for different temperatures (580, 600, 620 and 640°C). The results are in agreement with the theory of Lifshitz-Slyozov-Ardell.
