· JVASP-50753· Ce2Th2O7

Ce2Th2O7 is a mixed rare-earth oxide ceramic compound combining cerium and thorium oxides, belonging to the family of actinide-bearing ceramics studied for nuclear and high-temperature applications. This material is primarily of research interest rather than established commercial use, investigated for its potential in nuclear fuel systems, radiation-resistant structural ceramics, and high-temperature oxidation barriers where the dual rare-earth/actinide composition may offer improved thermal stability and resistance to radiation damage compared to single-phase alternatives.
