在温和的温度和压力条件下，用氢氧化钾水溶液沉淀金属硝酸盐制备氧化铈纳米颗粒。在200- 230 ℃下得到各种类型的氧化铈粉末。合成颗粒的平均粒径在10-50 nm之间，颗粒物相为晶态。讨论了起始溶液浓度、起始溶液pH值、反应温度和反应时间等工艺参数对反应的影响。(C)2002 Elsevier Science B. V.保留所有紧身衣。
The cerium oxide nanosize particles were prepared under mild temperature and pressure conditions by precipitation from metal nitrates with aqueous potassium hydroxide. Various types of cerium oxide powders were obtained at 200-230degreesC. The average size of synthesized particles was in the range of 10-50 nm and the phase of synthesized particles was crystalline. The effects of synthesis parameters, such as the concentration of starting solution, pH of starting solution, reaction temperature and time, are discussed. (C) 2002 Elsevier Science B.V.
