Pr1 Co1 O3
semiconductor· Pr1 Co1 O3
PrCoO₃ (praseodymium cobalt oxide) is a perovskite-structured ceramic semiconductor combining rare-earth and transition-metal elements. This material is primarily of research interest for electrochemical applications, particularly as a cathode material in solid oxide fuel cells (SOFCs) and oxygen reduction catalysts, where its mixed ionic-electronic conductivity and catalytic activity offer advantages over conventional perovskites. Engineers select this compound for high-temperature electrochemical devices where tolerance to redox cycling and chemical stability in oxidizing atmospheres are critical, though it remains less mature than established alternatives like lanthanum strontium manganite (LSM).

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.
