dc.description.abstractThe aim of this work was to investigate the effect of previous treatments at high pressures on the crystallization kinetics of monolithic samples of a Li2O-2SiO(2) (LS2) glass. The glass transition temperature (T-g) and the temperature of the onset of crystallization (T-p) obtained by differential thermal analyses (DTA) were measured for LS2 glass samples submitted to isostatic pressures ranging from 2.5 to 7.7 GPa during 5 min at room temperature. The observed systematic changes in T-g and T-p were probably related to the cracks induced by high pressure inside the monolithic samples and in its surface. Away from the cracks, the nucleation density slightly decreased as a function of pressure but along the cracks, the nucleation density was significantly higher. (C) 2010 Elsevier B.V.
