The structure and properties of lithium aluminosilicate glasses containing Y203 were investigated by X-ray diffraction （XRD）, scanning electron microscopy （SEM）, differential thermal analysis （DTA） and Raman spectroscopy. Effects of yttria on the viscosity of LAS glasses were investigated, and found that the introduction of yttria effectively decreased the viscosity of LAS glasses. In Raman spectra of initial glasses it is shown the starting glasses are in almost complete disorder, since all bands are weak and broad. In the spectra of heat-treated specimens some new narrow bands appear and increase in intensity, and the frequency changes with varied yttria addition. The DTA and XRD results show that yttria controlled the crystallization of LAS glasses by increasing the crystallization peak temperature （T）, however, the main crystalline phase of glass-ceramics was β-spodumene.
The golden and ultraviolet-absorbed CeO2-TiO2 film was prepared on soda-lime glass substrate with the thickness of 2 mm via the sol-gel method. The transmission spectra in range of 200 nm-800 nm were measured, and the crystallization, the abrasion and acid resistance were also investigated. The appropriate sol contents and heat-treatment schedule were determined. The results indicate that the appropriate molar ratio of Ce/Ti was 3：5 to 5：6. The ultraviolet-absorbance ability increased with the increase of the Ce/Ti molar ratio, but when the Ce/Ti molar ratio was higher than 1.5, the homogeneity of the film was deteriorated. With the increase of heat-treatment temperature, the main wavelengths of the color of the coated glasses were equal, but the color＇ s saturation decreased; the transmission peaks were the same, while the intensity of the peaks decreased. The roughness, abrasion and acid resistance of the film were also enhanced at the same time. The appropriate heat- treatment temperature may be 340℃.
