Materials and methods Glass-ceramics preparation The glass compositions of selcted Li-Al-Si glass-ceramics were selected according to our earlier research result [5], as listed in Table 1.
Raw materials were mixed for 5 h at ball milling, melted for 4 h at 1853 K and then annealed for 1h at 873K to eliminate internal stress.
