· JVASP-29309· SmFePO

SmFePO is an iron phosphate ceramic compound containing samarium, belonging to the phosphate ceramics family. This material is primarily of research interest for nuclear waste immobilization and thermal management applications, where its dense crystal structure and chemical stability offer advantages in isolating radioactive ions within a durable glassy or crystalline matrix. SmFePO and related rare-earth iron phosphates are being investigated as alternatives to traditional borosilicate glass for high-level waste forms, particularly for lanthanide-rich waste streams, due to their enhanced chemical durability and thermal properties.
