Description
Key Properties & Advantages
LSCF6428’s performance is defined by its optimized perovskite structure and tailored elemental composition:
Ultra-Fine Particle Size (0.2–0.4 μm): Maximizes surface-to-volume ratio, creating abundant active sites for ORR and accelerating reaction kinetics—critical for high-efficiency IT-SOFC cathodes.
High Specific Surface Area (10–15 m²/g): Enhances ion and electron transport at the electrode-electrolyte interface, reducing polarization resistance and improving fuel cell power density.
Low Moisture Content (<1 wt.%): Prevents agglomeration during storage and processing, ensuring uniform dispersion in slurries or composite electrodes (e.g., with GDC/YSZ electrolytes).
Balanced Co/Fe Ratio: The 0.2 Co : 0.8 Fe ratio optimizes both oxygen ion conductivity (from Co) and thermal/chemical stability (from Fe), enabling long-term operation at 600–800°C.
Perovskite Structural Stability: Retains its ABO₃ crystal structure under oxidizing and reducing atmospheres, with minimal sintering at operating temperatures—ensuring durability in SOFC stacks.
Core Applications
Intermediate-Temperature Solid Oxide Fuel Cells (IT-SOFCs)
LSCF6428 is the gold standard for IT-SOFC cathodes, where efficiency and stability are paramount:
Cathode Layers: Delivers exceptional ORR activity at 600–750°C, a temperature range that reduces material degradation and lowers system costs compared to high-temperature SOFCs.
Composite Cathodes: Blends seamlessly with electrolytes like GDC (gadolinium-doped ceria) to form functional gradients, optimizing ion conduction and reducing interfacial resistance.
Large-Scale Stacks: Supports scalable production of SOFC stacks for distributed power generation, leveraging its stability and consistent performance.
Oxygen Separation Membranes
Oxygen Permeation Layers: Enables efficient oxygen transport through dense membranes, suitable for industrial gas purification (e.g., O₂ enrichment from air) and syngas production.
Catalysis & Environmental Remediation
Oxidation Catalysis: Catalyzes reactions such as CO oxidation and volatile organic compound (VOC) degradation, leveraging its high surface area and redox-active Co/Fe sites.
Its chemical composition is La₀.₆Sr₀.₄Co₀.₂Fe₀.₈O₃₋δ (perovskite structure); the particle size (D50) is determined by laser diffraction to be 0.2–0.4 μm; the specific surface area measured by the BET method is 10–15 m²/g; the moisture content detected by Karl Fischer titration is less than 1 wt.%; the crystal structure is rhombohedral perovskite; and the appearance is a black to dark gray crystalline powder.
Quality Assurance
Each batch of LSCF6428 undergoes rigorous testing to ensure reliability:
X-ray diffraction (XRD) to confirm perovskite phase purity and crystal structure.
Particle size analysis (laser diffraction) to verify 0.2–0.4 μm distribution.
BET surface area measurement to validate 10–15 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.
