8Y-CSZ Zirconia Powder
CAS Number: 1314-23-4
8mol% yttria-stabilized cubic zirconia (8Y-CSZ) powder, equivalent to Tosoh TZ-8Y. Engineered for solid oxide fuel cells (SOFC), thermal barrier coatings (TBC), and oxygen sensor electrolytes. Y₂O₃ content ~13.6% ensures fully stabilized cubic phase with high ionic conductivity (0.10–0.13 S/cm at 1000°C).
