· JVASP-105837· PmAs3

PmAs3 is a rare-earth pnictide ceramic compound combining promethium with arsenic, belonging to the class of intermetallic ceramics studied primarily in materials research rather than established industrial production. This material is of interest in solid-state physics and nuclear materials research due to promethium's radioactive properties, with potential applications in radiation-hardened electronics, neutron absorbers, or specialized nuclear fuel studies. The compound represents an experimental material system where the combination of rare-earth and pnictide chemistry offers unique electronic or thermal properties not readily available in conventional ceramics, though commercial viability and widespread engineering adoption remain limited to specialized research and nuclear sectors.
