· JVASP-50087· Tb3SbO7

Tb3SbO7 is a rare-earth oxide ceramic compound belonging to the pyrochlore family, combining terbium and antimony oxides in a highly ordered crystal structure. This material is primarily investigated in research contexts for applications requiring high-temperature stability, radiation resistance, and ionic conductivity, making it of interest for advanced nuclear and energy-related technologies. Compared to conventional refractory ceramics, pyrochlore compositions like this one offer unique phonon-scattering behavior and tunable defect chemistry, positioning them as candidates for next-generation thermal barrier coatings and nuclear fuel matrices where tolerance to extreme irradiation is critical.
