Ho4 Zr4 O14
semiconductor· Ho4 Zr4 O14
Ho₄Zr₄O₁₄ is a rare-earth zirconium oxide ceramic compound combining holmium and zirconium in a mixed-oxide crystal structure. This material belongs to the family of rare-earth zirconate ceramics, which are primarily of research and developmental interest for high-temperature applications where thermal stability and chemical inertness are critical. The holmium-zirconium oxide system is being investigated for advanced thermal barrier coatings, nuclear fuel cladding candidates, and solid-state electrolyte applications, where the rare-earth doping can enhance phase stability and oxygen-ion conductivity compared to conventional zirconia systems.
