AuPmO3

AuPmO3 is an experimental rare-earth oxide ceramic compound containing gold, promethium, and oxygen. This material exists primarily in research contexts rather than established industrial production, as promethium is a synthetic radioactive element with limited availability. The material family of rare-earth oxides with noble metals is of interest for potential applications in high-temperature ceramics, radiation-resistant materials, and specialized electronic/photonic devices, though AuPmO3 specifically remains largely unexplored outside fundamental materials science investigation.
