以氯化镁、氯化锰、氢氧化钠及碳酸钠为原料，采用共沉淀法合成镁锰双金属氢氧化物(Mg-Mn-LDH)。探讨镁锰摩尔比、反应温度、反应时间等条件对镁锰双金属氢氧化物(Mg-Mn-LDH)结晶性的影响。通过 XRD和 SEM对产物结晶性、组成结构等进行表征。实验结果表明，在镁锰摩尔比3∶1、反应温度40℃、反应3 h、长陈化时间和反应体系 pH 13下，制备出的产物的结晶性最好，层状结构也最清晰。

Double hydroxide of Mg-Mn(Mg-Mn-LDH)was prepared by method of coprecipitation using magnesium chloride,manganese chloride,sodium hydroxide and sodium carbonate as raw materials.The paper aims to investigate the effect of Mg Mn molar ratio,reaction temperature,reaction time and other conditions on the crystallinity of double metal hydroxide,magnesium and manganese (Mg-Mn-LDH). Characterized by XRD and SEM,the results showed that when the ratio Mg to Mn was 3∶1 ,the reaction temperature was controlled at 40℃,reaction time 3 h,the long aging crystallization time,pH value was 1 3 ,there was a high degree of crystallinity,the layered structure for the product was clear.
