· JVASP-38737· Pm5Mg

Pm5Mg is a rare-earth intermetallic ceramic compound containing promethium and magnesium, representing an experimental material in the radioactive rare-earth ceramics family. While promethium's radioactive nature (beta emitter) severely limits practical applications, this compound is primarily of research interest for studying thermal properties, radiation effects on ceramics, and potential high-temperature structural behavior in specialized nuclear or space environments. Its rarity and handling requirements make it unsuitable for conventional engineering applications, with any use restricted to controlled laboratory settings or advanced research programs.
