【Abstract】 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.更多还原
