Pm2S3 is a rare-earth sulfide ceramic compound containing promethium and sulfur, belonging to the family of lanthanide chalcogenides. This material is primarily of research and specialized nuclear applications interest, as promethium is a radioactive element produced in nuclear reactors; it is not commonly employed in conventional engineering practice. The material's potential applications leverage the thermal and radiative properties of promethium-bearing ceramics in niche areas such as radioisotope thermoelectric generators and specialized nuclear instrumentation, though practical use remains limited due to handling constraints, regulatory oversight, and the availability of more stable alternative materials for most industrial applications.
