摘　　要：以六水氯化镁和氨水为原料,在无模板剂存在条件下利用水热法合成出了具有规则形状的氢氧化镁六方片层及其组合玫瑰花球纳米结构,并分析了镁离子浓度、反应温度、反应时间、表面活性剂对晶体制备的影响。通过SEM和SAED观察样品的显微形貌及晶体结构,厚度为20 nm^50 nm,为单晶物质。通过XRD测定样品的晶相结构,产物为结晶性Mg(OH)2。By using a non-template hydrothermal method,regular hexagonal nano-plates and the combined rose ball nano-structures of magnesium hydroxide were prepared with magnesium chloride hexahydrate and ammonium hydroxide as raw material. This paper analyzed the influence of the reaction condition including reaction temperature,reaction time and surfactant on the preparation of crystal. The product was single crystal material with the average thickness of 20 nm ~ 50 nm,which the morphology and crystal structure was investigated by SEM and SAED. Crystalline structure of the samples were characterized by XRD and the product was Mg（ OH）2.
