摘　　要：以CoCl2.6H2O和(NH4)3PO4.3H2O为原料,在适量表面活性剂聚乙二醇(PEG-400)的存在下,在室温(R.T.)研磨反应混合物进行固相反应,将反应混合物在不同的温度(80℃,60℃,R.T.)保温陈化4 h,用水洗去混合物中可溶性的无机盐,在110℃下烘干2 h,得到一水合磷酸钴铵晶体材料。用XRD,IR,SEM及TG/DTA对产物进行了表征。结果表明,3种不同保温温度均得到具有正交晶系物相,空间群为Pmn21(31)的片状(NH4)3CoPO4.H2O晶体材料。The crystalline（NH4）3CoPO4·H2O was prepared in the presence of surfactant PEG-400 with fully ground CoCl2·6H2O and（NH4）3PO4·3H2O as raw materials in solid-state at room temperature,aged at different temperatures（80 ℃,60 ℃,R.T.） for 4 h,then washed with water to remove soluble inorganic salts and dried at 110 ℃ for 2 h to obtain the crystals of ammonium cobalt phosphate hydrate.The products were characterized with XRD,IR,SEM and TG/DTA.The results showed that（NH4）3CoPO4·H2O crystalline sheets with orthorhombic structure and space group Pmn21（31） developed at all three temperatures.
