· JVASP-30196· Ce2Dy2O7

Ce2Dy2O7 is a rare-earth oxide ceramic belonging to the pyrochlore family, combining cerium and dysprosium oxides in a stable crystalline structure. This material is primarily investigated for high-temperature thermal barrier coating (TBC) applications in aerospace and power generation, where its rare-earth composition offers improved thermal stability and lower thermal conductivity compared to conventional yttria-stabilized zirconia (YSZ). The cerium-dysprosium combination is notable for enhanced chemical durability in oxidizing and molten salt environments, making it particularly attractive for next-generation gas turbine engines and concentrated solar power systems operating at extreme temperatures.
