· TmPmO3

TmPmO3 is a rare-earth oxide ceramic compound containing thulium and promethium in a perovskite-related crystal structure. This is a research-phase material studied primarily for its potential in high-temperature ceramics and radiation-resistant applications, as promethium's radioactive nature and thulium's refractory properties offer unique combinations not found in conventional oxide ceramics. While not yet established in mainstream engineering practice, materials in this family are of interest for extreme environment applications where thermal stability and radiation tolerance are critical.
