Description
BCZYYb (Barium Cerate-Zirconate Yttrium-Ytterbium Oxide)
The Next-Generation Protonic Ceramic Electrolyte Material
BCZYYb is a high-performance perovskite-type oxide. By co-doping the Barium Cerate-Zirconate matrix with Yttrium (Y) and Ytterbium (Yb), this material achieves an optimal balance between chemical stability and high proton conductivity. It serves as a critical raw material for Intermediate-Temperature Solid Oxide Fuel Cells (IT-SOFCs) and Reversible Protonic Ceramic Electrochemical Cells (R-PCECs).
Key Technical Advantages
- Synergistic Doping for Stability & Performance: The inclusion of Zirconium (Zr) enhances stability against
and moisture, while the Cerium (Ce) and dual-doping strategy (Y/Yb) ensure superior protonic conductivity at 400–600°C.
- Nano-scale Particle Distribution: With an average particle size of 30–60 nm and a high specific surface area of 20–50 m²/g, the powder exhibits excellent sintering activity for fabricating dense electrolyte membranes.
- High Phase Purity: Features a single-phase Orthorhombic (O-phase) structure with purity
. Strict control over metallic and non-metallic impurities ensures consistent electrochemical reliability.
