Y4 Zr4 O14
semiconductor· Y4 Zr4 O14
Y₄Zr₄O₁₄ is a mixed rare-earth zirconium oxide ceramic compound that belongs to the family of yttria-zirconia systems, which are known for their ionic conductivity and thermal stability. This material is primarily investigated in research contexts for solid oxide fuel cell (SOFC) electrolytes and thermal barrier coatings, where the combined yttrium and zirconium oxides provide enhanced oxygen ion transport and thermal protection compared to single-phase alternatives. Its potential lies in high-temperature electrochemical applications and advanced ceramic composites where thermal cycling resistance and chemical stability are critical.
