There were some “whiskers” of metallic luster on the surface after thermal treatment under some special conditions. The “whiskers” were verified as Bi and Al via scanning electron microscopy (SEM), energy dispersive X-ray analysis (EDXA), X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS), which can react with borate solution. The effects of technological parameters such as heat-treatment temperature T, precursor concentration C, and heating rate V have been explored. It is shown that the formation difficulty of Bi and Al increases with the T, C and decreases with V. 关键词： Sol-Gel; Bismuth titanium oxide (BTO); EDXA; XPS (浏览全文) 发表日期： 2006年07月06日 同行评议：
