CeZrO4 is a mixed cerium-zirconium oxide ceramic belonging to the fluorite-structure oxide family, combining the thermal and chemical properties of ceria and zirconia systems. This material is primarily investigated for high-temperature applications including thermal barrier coatings, solid oxide fuel cells, and oxygen-ion conductors, where its mixed-valence cation system offers improved thermal stability and ionic conductivity compared to single-component oxides. Engineers select CeZrO4 for demanding environments requiring thermal shock resistance and chemical inertness, particularly in energy conversion and thermal protection systems where conventional refractory materials face durability limits.
