چکیده مقاله:
In order to fabrication of transparent glass-ceramics with Li-mica nano crystals, the glasses with chemical composition of 94.9 mass% Lid-MgAlSiscF, (x=0.5) with 5.1 mass% MgF2 were crystallized. The glasses were fabricated via the conventional melt-quenching technique. Mica crystals were precipitated in the glass phase by later heat treatment. Glass samples had glass transition temperature (T), 557 C, softening temperature (T,), 603 °C, and crystallization peak temperature (T), 655 °C. The fine mica crystals with size of <50 nm were precipitated at 600C in one continuous glass phase of the binodal phase separation. It s confirmed that both as-quenched and heat-treated samples are transparent in the visible wave length.
