Description

Key Properties & Advantages
8YSZ??s superior performance stems from its stabilized cubic structure and optimized particle characteristics:

Ultra-Fine Particle Size (0.2?C0.4 ??m): Enables dense sintering at lower temperatures (1200?C1400??C), reducing energy consumption during fabrication while ensuring uniform microstructure in thin films or bulk components.
High Specific Surface Area (8?C14 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?C10?1 S/cm) at 800?C1000??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) 8YSZ is the industry-standard electrolyte for high-temperature SOFCs, where ionic conductivity and stability are critical: SOFC Electrolytes: Functions as a dense, gas-impermeable membrane that conducts oxygen ions from cathode to anode, enabling efficient electrochemical energy conversion at 800?C1000??C. Composite Electrodes: Blends 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: Used in TBCs for gas turbines, jet engines, and industrial furnaces, leveraging its low thermal conductivity to insulate metal components from extreme heat (up to 1200??C), extending service life. Oxygen Sensors & Ceramic Components Zirconia-Based Oxygen Sensors: Acts as a solid electrolyte in automotive and industrial oxygen sensors, enabling precise monitoring of O? levels in exhaust streams or combustion processes. High-Temperature Ceramic Parts: Fabricated into crucibles, furnace liners, and wear-resistant components, thanks to its mechanical strength and chemical inertness. Technical Specifications The parameter details are as follows: the chemical composition is (Y?O?)?.??(ZrO?)?.?? (8 mol% yttria-stabilized zirconia); the particle size (D50) is 0.2?C0.4 ??m (determined by laser diffraction); the specific surface area is 8?C14 m2/g (measured by the BET method); the moisture content is <1 wt.% (tested by Karl Fischer titration); the crystal structure is stabilized cubic zirconia; the color is white crystalline powder X-ray diffraction (XRD) to confirm cubic phase purity and yttria doping uniformity. Particle size analysis (laser diffraction) to verify 0.2?C0.4 ??m distribution. BET surface area measurement to validate 8?C14 m2/g range. Moisture content testing to ensure compliance with <1 wt.% specification. A certificate of analysis (CoA) is provided with each order, documenting batch-specific properties.
