摘 要:采用溶胶-凝胶工艺制备了Ti-17%Si 钛硅二元氧化物纳米材料,利用扫描差热 (DTA)、红外光谱(IR)、X射线衍射(XRD)和透射电子显微镜(TEM)等分析方法研究了其组织结构特点,并与含钛单元系相比较,结果表明,Si元素的添加稳定了锐钛矿相结构, 也使得产物的纳米尺度变得更为细小。
Abstract: Ti-17% Si binary oxide nano-materials were prapared by a Sol-gel technique. The morphologies and structures of the materials were studied by DTA, IR, XRD and TEM. After comparing with the monobasic oxide , the results indicated that the adding of Si element makes the anatase structure stabler and the nanocrystal finer.
