摘　　要：以硝酸钴 ,硝酸钕 ,柠檬酸为原料 ,采用溶胶 -凝胶法制得Co-Nd复合氧化物的前驱体 ,分别置于马弗炉中于 5 0 0、60 0、80 0、1 0 0 0℃下煅烧得黑色的微粒 ,用X射线衍射技术对产物的物相 ,粒径进行了表征。结果表明 :80 0℃的产物晶型最好 ,且分布均匀 ,达到纳米级 ,平均粒径为 3 0nm。Co-Nd complex oxid precurrsor was prepared from Co(NO 3) 2·6H 2O, Nd(NO 3) 3·nH 2O and citric acid by Sol-gel method.precursor was calcined at different temperatures (500 ℃、600 ℃、800 ℃,1 000 ℃) in muffle. Then black particles were prepared and characterized by X-radial diffraction. The results indicated the obtained product crystalstruction at 800 ℃ was the best. The average particle size was 30 nm.
