Abstract: The effect of different amount of TiO2 and thermal-treatment on the fabrication of nanocrystalline spinel glassceramics from the Li2O-MgO-Al2O3 -SiO2 system With the aid of DSC XRD and SEM is analysed. Nucleating mechanism is also discussed to find that enough TiO2 content ( no less than 7~ 5% D is the key to obtain nanocrystalline. Experiment results show that glass-ceramics with uniformly dispersed spinel crystals about 80nm in size can be produced when TiO2 content is 10% and such glass are heat-treated under appropriate conditions. The result glass-ceramics are suitable for substrates of high-performance hard-disk according to the characteristic test.

Key words: nano-phase,  spinel,  glass-ceramics,  TiO2 ,  substrate
