PmCeO3

PmCeO3 is a rare-earth oxide ceramic compound combining promethium and cerium in a perovskite-based structure, primarily investigated in materials research rather than established in widespread industrial production. This material belongs to the rare-earth oxide family and is of interest for its potential in high-temperature applications, radiation tolerance, and ionic conductivity, making it relevant for advanced energy conversion and nuclear-related technologies where traditional ceramics may degrade. The combination of promethium (a radioactive element) with cerium oxide suggests specialized applications in radiation-resistant materials or nuclear fuel matrices, though its use remains largely experimental and limited to research institutions with appropriate facilities.
