Lithium aluminosilicate (LAS) glasses are generally difficult to prepare because of their high melting temperature. In this study, the preparation of LAS glasses was achieved at a relatively low melting temperature. The batch containing MgO-ZnO-Li 2 O-Al 2 O 3 -SiO 2 was melted in a platinum crucible at 1550°C for 2 h and was then followed by two- or three-step heat...
