Description
8YSZ (8 mol% Yttria-Stabilized Zirconia) Powder
Full Product Datasheet
Key Properties & Advantages
8YSZ’s superior performance stems from its stabilized cubic structure and optimized particle characteristics:
- Ultra-Fine Particle Size (0.2–0.4 μm): Enables dense sintering at lower temperatures (1200–1400°C), reducing energy consumption during fabrication while ensuring uniform microstructure in thin films or bulk components.
- High Specific Surface Area (8–14 m²/g): Facilitates efficient sintering and promotes strong adhesion in coatings or composite materials (e.g., with LSM cathodes in SOFCs).
- Low Moisture Content (<1 wt.%): Prevents agglomeration during storage and processing, ensuring uniform dispersion in slurries, pastes, or green bodies.
- Stabilized Cubic Zirconia Phase: 8 mol% yttria doping eliminates phase transitions (monoclinic ↔ tetragonal) that cause cracking in pure zirconia, ensuring structural integrity at temperatures up to 1200°C.
- High Oxygen Ion Conductivity: Exhibits exceptional ionic conductivity (10⁻²–10⁻¹ S/cm) at 800–1000°C, making it the gold standard for SOFC electrolytes—enabling efficient oxygen transport between cathode and anode.
- Excellent Thermal & Chemical Resistance: Resists corrosion in oxidizing and reducing atmospheres, with low thermal conductivity (ideal for TBCs) and high mechanical strength.
Core Applications
Solid Oxide Fuel Cells (SOFCs)
- SOFC Electrolytes: Dense, gas-impermeable membrane conducting oxygen ions from cathode to anode for efficient electrochemical energy conversion at 800–1000°C.
- Composite Electrodes: Blended with LSM (lanthanum strontium manganite) to form robust cathode composites, optimizing ion/electron transport at the electrode-electrolyte interface.
Thermal Barrier Coatings (TBCs)
- High-temperature protection for gas turbines, jet engines, and industrial furnaces. Low thermal conductivity insulates metal components up to 1200°C, extending service life.
Oxygen Sensors & Ceramic Components
- Zirconia-Based Oxygen Sensors: Solid electrolyte for automotive and industrial O₂ monitoring in exhaust or combustion processes.
- High-Temperature Ceramic Parts: Crucibles, furnace liners, and wear-resistant components utilizing high mechanical strength and chemical inertness.
