Sm1 Th4 O10

Sm₁Th₄O₁₀ is a rare-earth–thorium mixed oxide ceramic compound combining samarium and thorium in an oxidic framework. This material is primarily of research and development interest rather than established commercial production, belonging to a family of actinide-rare earth ceramics explored for high-temperature stability and radiation tolerance. Potential applications lie in advanced nuclear fuel forms, refractory components for extreme thermal environments, and as a candidate material for back-end nuclear waste immobilization strategies where thorium-bearing phases offer chemical durability and thermal stability advantages over conventional alternatives.
