· Ce2 Hf2 O8

Ce₂Hf₂O₈ is a mixed rare-earth hafnium oxide ceramic compound combining cerium and hafnium in a complex oxide lattice. This material belongs to the family of high-entropy or multi-component ceramics being actively researched for extreme-environment applications, where the dual rare-earth composition offers potential advantages in thermal stability, radiation resistance, and chemical durability compared to single-component oxides.
