ABSTRACTChemically ultra-homogeneous gels have been prepared, in the SiO2-Al2O3 system, using new metal-organic precursors with Al-O-Si linkages. By thermal treatment at 900°C, transparent monolithic gels lead to aluminosilicate glasses and above 1000°C, to optically transparent glass-ceramics (for instance by homogeneous crystallization of mullite in an amorphous silica matrix).

Transparent glass with composition 65LiNbO3-35SiO2 was fabricated via the conventional melt-quenching technique. Glass-ceramics containing nanoscale (less than 100 nm) rhombohedral lithium niobate crystals were successfully produced by annealing the respective glass at various temperatures (600, 650 700 and 975 °C) for 1 h. The result of optical transmission spectra shows that the quenched sample is optically transparent. Transparent samples should possess crystals << 200 nm and have a narrow distribution of crystal sizes.

In this research, the effects of SrFe12O19: SF on optical and dielectric properties of Na2O-CaO-P2O5 glasses were investigated. From the study, the optically transparent glass, SF/Na2O-CaO-P2O5, system was successfully prepared by melt-quench method. The composition of SF/Na2O-CaO-P2O5 used in this study are ranging between 5-20 wt.% SF. It was found that the addition of SF enhanced the conductivity, but in turn reduced the percentage of transmittance in the glasses. The glasses subjected to be adding SF contents at higher than 15 wt% were opaque, while the lower range gave highly transparent glass ceramics. The dielectric constant (ɛr) of the SF/Na2O-CaO-P2O5 glasses were improved by increasing the content of SF, which in turn plays an important role in controlling the properties of the glass ceramics, including physical, optical, and dielectric properties.
