Abstract: The influences of the molar ratios of Al2O3/Na2O (MAN) and SiO2/Al2O3 (MSA)on the crystallization properties of the glass were studied in this work based on the sodium-aluminum-silicate glass system containing Y2O3 and ZrO2. The results show that, when MAN<1, sodium nepheline crystals precipitate on the surface of the glass after heat treatment. When MAN>1, yttrium zirconate nanocrystals can be formed in the whole bulk glass, and the glass-ceramics can maintain a high visible light transmittance of 90%. For glass with fixed MAN, adjusting its MSA can also achieve the precipitation of yttrium zirconate nanocrystals, and the size of the precipitated crystals decreases as MSA increases. Furthermore, as the heat treatment temperature rises, the size of nanocrystals in glass-ceramic nanocrystals as well as Vickers hardness increases.

Key words: sodium-aluminum-silicate glass, crystallization behavior, heat treatment, yttrium zirconate nanocrystal, transparent glass-ceramics, Vickers hardness
