摘　　要：利用Sol-Gel法,在制备ZnO粉体过程中添加不同比例的Y2O3、CeO2、La2O3、Eu2O3等稀土氧化物。然后在600℃煅烧2h后进行24小时的球磨,过300目的标准筛得到粒度分布均匀的掺杂稀土氧化物的ZnO复合粉体。利用DTA、XRD、SEM分别对ZnO复合粉体的热性质和物质构成、形貌、粒度分布、晶体结构进行了表征,从而得到最佳工艺参数。In the preparation of ZnO powders, different proportions of rare earth oxides （Y203, CeO2, La203, Eu203） were added by sol-gel method, and then the ZnO composite powders were calcined at 300℃ over 2 hours and ball milled over 24 hours. Finally, ZnO composite powders were obtained through a 300 mesh standard sieve. The thermal properties, material composition, morphology, particle size distribution and crystal structure of ZnO composite powders were characterized by DTA, XRD and SEM respectively, and the best processing parameters were determined.
