ceramic

· JVASP-37334· Sm3Th

Sm₃Th is a rare-earth ceramic compound composed of samarium and thorium, belonging to the family of intermetallic and ceramic phases that form in rare-earth–actinide systems. This material is primarily of research and academic interest, explored for its potential in high-temperature applications and as a model system for understanding phase stability in complex ceramic compositions containing both lanthanides and actinides. Its practical industrial use remains limited; it is encountered mainly in specialized nuclear materials research, materials science studies of phase diagrams, and fundamental investigations into rare-earth–thorium interactions for potential advanced ceramics or refractory applications.
