Praseodymium oxide CAS#12037-29-5

Praseodymium Oxide, or praseodymia, is a dark brown powder that is insoluble in water and only in strong acids. Praseodymium Oxide is stable under average temperatures and pressures. Praseodymium Oxide is a rare earth oxide compound, which is a basic anhydride and can react with acids and with potent reducing agents in redox reactions. Rare earth oxide compounds contain at least one oxygen anion and one metallic cation. They are typically insoluble in aqueous solutions (water) and extremely stable, which makes them useful in ceramic structures. For this reason, Praseodymium Oxide has a wide range of applications, from producing clay bowls to advanced electronics. Praseodymium Oxide is also valuable for lightweight structural components in aerospace and electrochemical applications such as fuel cells due to its ionic conductivity.
