摘要
以硝酸铝为原料，利用十六烷基三甲基溴化胺（CTAB）为模板剂，通过水热合成技术制备了棒状氧化铝材料。通过TEM及SEM分析表明，水合氧化铝产物呈长板片形结构，长径比在1：10左右；经500℃煅烧获得的γ-Al2O3呈棒状，在棒表面有纳米孔洞存在；经1200℃煅烧获得的α-Al2O3则呈现致密的晶粒串烧在一起的棒状结构，但棒的直径不呈等径状态。
Alumina nanorods were synthesized by hydrothermal technique with Al（NO3）3 as raw material and CTAB as template. TEM and SEM results showed that the structure of hydro-alumina was feature film. The ratio of its length and width was 1：10 or so. The structure of γ-A12O3 （sintered at 500℃ was rob, and there were nano-holes on the rods. The structure of α-A12O3 （sintered at 1200℃） was dense powder rod, and its diameter was unlikeness.
