摘 要: 采用溶膠-凝膠工藝制備了Ti-17%Si 鈦硅二元氧化物納米材料，利用掃描差熱 (DTA)、紅外光譜(IR)、X射線衍射(XRD)和透射電子顯微鏡(TEM)等分析方法研究了其組織結(jié)構(gòu)特點(diǎn)，并與含鈦單元系相比較，結(jié)果表明，Si元素的添加穩(wěn)定了銳鈦礦相結(jié)構(gòu)， 也使得產(chǎn)物的納米尺度變得更為細(xì)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.
