· JVASP-53065· Nd2Zr2O7

Nd₂Zr₂O₇ is a rare-earth zirconate ceramic compound belonging to the pyrochlore family, composed of neodymium oxide and zirconia in a 1:1 ratio. This material is primarily investigated in advanced thermal and environmental barrier coating systems, particularly for high-temperature aerospace applications where superior thermal stability and chemical resistance are required. Its use remains largely in the research and development phase, where it shows promise as an alternative to conventional thermal barrier coatings due to its enhanced durability in extreme oxidizing and corrosive environments found in jet engines and hypersonic vehicles.
