Abstract A systematic study of the crystallization behaviour of some glass melts derived from the eutectic Li2Si2O5-MgSiO3-SiO2 (930°c) in the Li2O-MgO-SiO2 system was carried out. The eutectic (930°c) composition was modified by introducing CaO and/or Al2O3 instead of MgO and Li2O on cation per cation basis respectively. These glass compositions were treated through different heat-treatment schedules using minor additives of CaF2 or TiO2 as nucleating agents. |
