【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．更多还原

【Abstract】 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-Al₂O₃ （sintered at 500℃） was rob,and there were nano-holes on the rods.The structure of α-Al₂O₃ （sintered at 1200℃） was dense powder rod,and its diameter was unlikeness.更多还原
