Praseodymium dioxide (PrO₂) is a rare-earth oxide ceramic compound that exhibits mixed-valence properties and oxygen-defect chemistry, making it distinct from typical refractory oxides. It is primarily investigated for applications requiring thermal stability, ionic conductivity, or catalytic function in high-temperature environments, including solid oxide fuel cells, oxygen sensors, and catalytic converter substrates where its oxygen-storage capacity and redox cycling behavior offer advantages over conventional alternatives.
