· JVASP-19663· PrO2

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.

Regulatory Screening

Environmental

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
