摘要
Materials in the lead zirconotitanate system possess useful and interesting electroopticaland piezoelectric properties.Because the sol-gel method possesses a number of desirableadvantages compared with conventional methods, it has been developed as an importantand potential process enabling the preparation of oxide glasses which are difficult or impos-sible to make by conventional methods.Recently,ZrO<sub>2</sub>-TiO<sub>2</sub> and ZrO<sub>2</sub>TiO<sub>2</sub>-SiO<sub>2</sub> with ahigh content of ZrO<sub>2</sub>,and PbO-TiO<sub>2</sub> with PbO were prepared by sol-gel process.
