· JVASP-50836· Tm2Sb2O7

Tm2Sb2O7 is a rare-earth oxide ceramic compound belonging to the pyrochlore family, composed of thulium and antimony oxides. This material is primarily investigated in advanced ceramics research for its potential thermal and structural properties at elevated temperatures, with particular interest in nuclear fuel applications and as a thermal barrier coating candidate. Its relatively high density and rare-earth composition make it notable for specialized high-temperature engineering environments where conventional ceramics may be insufficient.
