Abstract

Graded oxide glasses in binary oxide systems (Si-Ti, Si-V, and Si-Zr) had been prepared by means of a sol -gel method combined with centrifugal processing. In the Si-Ti and Si-V oxide systems, the graded oxide glasses, whose composition continuously changed with dimension in molecular scale, were prepared. The FT-IR analysis showed that infrared absorption peaks of Si-O-Si stretching and bending shifted, and Ti-O-Si or V-O-Si bands appeared with increasing the concentration of Ti or V, respectively. In the Si-Zr oxide system, the graded oxide glass in which the ZrO 2 nanocrystals appeared in the high gravity region was prepared.
