· JVASP-21219· Pr2Sn2O7

Pr₂Sn₂O₇ is a rare-earth tin oxide ceramic belonging to the pyrochlore family, composed of praseodymium and tin oxides. This material is primarily investigated in research contexts for thermal barrier coatings and advanced ceramics, where its thermal stability and rare-earth chemistry offer potential advantages in high-temperature oxidation resistance compared to conventional zirconia-based systems. The pyrochlore structure is notable for its ability to accommodate point defects and maintain phase stability at elevated temperatures, making it of interest for aerospace and energy applications, though industrial adoption remains limited.
