2、d then it was mixed with a solution of lactic acid dissolved tetra-n-butyl titanate, subsequently, water was added to adjust sol concentration. The obtained sols or gels were characterized by Ultraviolet-Visible Spectrophotometer (UV), differential thermal analysis and thermo-gravimetry (TG-DTA), in-situ Raman, and high-temperature X-ray diffraction (HT-XRD). Results show that the BTO sol can keep stable for more than one year and completely convert into BTO at 533. 关键词： Sol-Gel; Bismuth titanate (BTO); In-situ Raman; HT-XRD (浏览全文) 发表日期： 2006年07月05日 同行评议： （暂时没有） 综合评价： （暂时没有） 修改稿：
