· JVASP-50856· Tm2Zr2O7

Tm2Zr2O7 is a rare-earth zirconate ceramic compound belonging to the pyrochlore family, composed of thulium and zirconium oxides. This material is primarily investigated in advanced ceramics research for high-temperature thermal barrier and structural applications, where its chemical stability and refractory characteristics make it a candidate alternative to conventional stabilized zirconia systems. Engineering interest centers on potential use in extreme thermal environments and corrosive conditions where conventional oxides may degrade.
