摘　　要：以氧氯化锆(ZrOC l2.8H2O)和磷酸三丁酯(C4H9O)3PO为原料,在正庚烷(C7H10)-十六烷基三甲基溴化铵(CTAB)/正丁醇(C4H9OH)-水的反向微乳体系中制备了Zr(HPO4)2.H2O,(H3O)+Zr2(PO4)3和Zr(HPO4)8.H2O三种不同结构的层柱状磷酸锆.运用扫描电子显微镜(SEM)、透射电子显微镜(TEM)和X射线衍射仪(XRD)等仪器对产物进行了表征,考察了不同微乳组成对磷酸锆结构及尺寸的影响.结果表明,微乳体系对层柱状磷酸锆的可控制合成具有广泛意义.Layered zirconium phosphates [ Zr（ HPO4 ） 2 · H2 O, （ H3 O） ^＋ Zr2 （ PO4 ） 3 and Zr （ HPO4 ） s· H2O ] were synthesized in water/oil（W/O） microemulsion system containing heptane, CTAB/butanol and water water. X-ray diffraction （XRD）, transmission electron microscopy （TEM） and scanning electron microscopy （SEM） were utilized to characterize the structure, morphology and size. It was found that the preparation of zirconium phosphate in W/O microemulsion could control structure based on the microemulsion composition （ i. e. three layered zirconium phosphates obtained with different ratio of water and oil） and morphology based on the reacted conditions （i. e. the size and morphology of a-zirconium phosphate can be controlled with different reacted time and temperature in microemulsion）. We believe that the simple synthetic method based on microemusion would benefit the controllable synthesis of zirconium phosphates greatly.
