| Research Abstract |
We have investigated the preparation condition of transparent glass-ceramics containing TiO2or ZnO nanocrystalllites. The preparation of dielectric nano-crystallites and metal nano-particles has also examined. We have demonstrated a surface orientated crystallization (ZnO) or a phase selective crystallization (TiO2) by careful investigation of relationship between chemical composition of glass and the precipitated crystalline phase. On the other hand, we examined correlation between the melt-temperature and network structure ofglass, and reported Pt nano-crystallites containing glass and the glass-ceramics. These results have shown that self-organized heterogeneous nanostructure can be made in a monolithic glass-ceramics.
