中文摘要:

      在十六烷基三甲基溴化铵（CTAB）-正己烷-正已醇-水组成的反相微乳液体系中合成纳米棒状碳酸锶。利用X射线衍射仪（XRD）和扫描电子显微镜（SEM）对样品进行表征。研究了反应物浓度、ω（水与表面活性剂CTAB的物质的量之比）值等因素对产物尺寸和形貌的影响，提出了在反相微乳液中棒状纳米碳酸锶的生长机理。

英文摘要:

      SrCO3 nanorods were synthesized in CTAB-hexane-hexanol-water reverse microemulsion.The products were characterized by X-ray diffraction and scanning electron microscope.The effects of different conditions such as reactant concentration and the molar ratio of water to surfactant CTAB on the morphology and the size of the products were studied.The growth mechanism of SrCO3 nanorods in reverse microemulsion was proposed.
