摘要
研究了直接沉淀法合成纳米结构氧化镨(Pr6O11)的相关工艺参数。通过控制沉淀反应过程中各工艺参数,可制备出组成分布较均匀、良好热稳定性的氧化镨纳米材料。实验结果表明:焙烧反应温度和焙烧反应时间是影响氧化镨粒度和晶型的主要因素。
Praseodymium oxide （Pr6O11） as a rare-earth functional materials,has been widely applied to the catalyst,ceramic pigments,oxygen storage materials,high-conductivity materials in many areas.The relevant process parameters of the direct synthesis been have studies which make the nano-structure of praseodymium oxide.By controlling the reaction during the deposition process parameters,the praseodymium oxide of good thermal stability be can maken.The experimental results show that：calcination temperature and calcination reaction time are the main factors that affect the nano-structure of praseodymium oxide.
