· JVASP-22075· Tm2Ge2O7

Tm2Ge2O7 is a rare-earth germanate ceramic compound containing thulium and germanium oxides, belonging to the family of pyrochlore or related rare-earth oxide structures. This material is primarily of research interest for applications requiring thermal stability and radiation resistance, particularly in advanced nuclear fuel forms, high-temperature insulation systems, and as a potential inert matrix for nuclear waste immobilization. Compared to conventional ceramics, rare-earth germanates offer distinct advantages in resisting radiation-induced amorphization and maintaining structural integrity under extreme thermal and chemical conditions, making them candidates for next-generation nuclear and aerospace thermal management applications.
