中文摘要：

以苎麻织物为生物模板，聚合氯化铝溶液为浸渍液，经浸渍、干燥获得前驱体，将前驱体经有氧煅烧制备出具有苎麻织物结构的 Al2 O3遗态材料．采用 TG 、XRD 、TEM 、SEM 和比表面积等检测技术，分别对材料的热失重、物相组成和显微结构进行了表征与分析．结果表明，1200℃下制备的 Al2 O3陶瓷成功地保留了苎麻织物的结构．不同浓度下制得的 Al2 O3具有不同的微观形貌．Al2 O3比表面积为9.94～30.07m 2？ g-1；平均孔径为5.02～6.2nm ．

英文摘要：

Based on bio-templating ,a new kind of Al2 O3 morph-genetic ceramic materials with the struc-ture of ramie fibers was prepared by calcining under aerobic environment from precursors ,which were prepared by impregnating poly-aluminum chloride solution .The phase composition and micro-structure of the materials were analyzed and characterized respectively by using thermo -gravimetric analysis （TG） ,X-ray diffraction （XRD） ,transmission electron microscope （TEM ） ,scanning electron micro-scope （SEM ） and H-2000PS2 system .The experimental results show that the Al2 O3 morph-genetic ce-ramic successfully reserved the ramie fibers structure .Under different concentration of aluminum ,the products have different morphology . BET test shows that the specific surface area is 9.94 ~30.07m2 ？ g- 1 and the average pore diameter is 5.02 ~ 6.2nm .
