中文摘要：

以MnCl2,NaNO3和H3PO4为原料,在温度为150℃的水热条件下反应12h制备出了棒状MnPO4·H2O单晶。利用X射线粉末衍射（XRD）、场发射扫描电镜（FESEM）和透射电子显微镜等手段对产物进行表征。结果表明,合成的产物为MnPO4.H2O单晶棒,直径为0.78～1.9μm,长度达几十微米。讨论了水热条件下反应时间对产物形貌的影响,并对棒状MnPO4.H2O单晶的生长机理进行了分析。

英文摘要：

Rod-like MnPO4·H2O single crystals were hydrothermally prepared by the reaction of MnCl2 with NaNO3 in the presence of H3PO4 at 150 ℃ for 12 h.The products were characterized by powder X-ray diffraction（XRD）,field-emission scanning electron microscopy（FESEM）,transmission electron microscopy（TEM）.The synthesized single-crystalline rods have diameters of 0.78-1.9 μm and lengths up to tens of micro meters.The influence of reaction time on the morphological evolution of the products under hydrothermal conditions is discussed,and a possible formation mechanism has been proposed on the growth of MnPO4·H2O single-crystalline rods.
