Product Description of Praseodymium Oxide CAS#12037-29-5
Praseodymium oxide, also known as praseodymia, is a dark brown powder that is insoluble in water and dissolves only in strong acids. It remains stable under normal temperature and pressure conditions. As a rare earth oxide, it behaves as a basic anhydride and can react with acids as well as strong reducing agents in redox reactions. Rare earth oxides typically consist of oxygen anions and metallic cations, are generally insoluble in water, and exhibit high chemical and thermal stability, making them well suited for ceramic structures. Consequently, praseodymium oxide is used in a wide range of applications, from traditional ceramic products to advanced electronic materials. Owing to its ionic conductivity, it is also applied in lightweight structural components for aerospace use and in electrochemical systems such as fuel cells.
