摘　　要：通过Al(NO3)3.9H2O水解,利用非均匀成核方法制备了MoS2/Al2O3的复合粉体,对复合粉体制备的工艺条件进行了研究,并利用SEM/EDS、TEM、XRD等方法对样品进行表征。结果表明:Al3+浓度、pH值、反应温度及滴定速度是影响包覆效果的主要因素,制备MoS2/Al2O3复合粉体的最佳工艺条件是Al3+浓度为0.17 mol/L,pH值为8,反应温度为75℃,滴定速度为3 mL/min。MoS2/Al2O3 composite powders were successfully prepared by heterogeneous nucleation method via Al（NO3）3·9H2O hydrolysis,and the preparation process conditions were studied.The samples of composite powders were characterized with SEM/EDS,TEM and XRD.The results showed that the main factors for coating effect includes Al3＋ concentration,pH value,temperature of reaction and titration rate.The optimum process conditions for preparing MoS2/Al2O3 composite powders are Al3＋ concentration for 0.17 mol/L,pH=8,temperature of reaction for 75 ℃ and titration rate for 3 mL/min.
