Description

Key Properties & Advantages
LSC641??s performance stems from its optimized perovskite structure and precise elemental composition:

Ultra-Fine Particle Size (0.2?C0.4 ??m): Enhances surface-to-volume ratio, maximizing active sites for oxygen reduction reactions (ORR) in SOFC cathodes and accelerating catalytic kinetics.
High Specific Surface Area (8?C12 m2/g): Provides abundant interfaces for ion and electron transport, improving electrochemical performance in energy devices.
Low Moisture Content (??1 wt.%): Ensures stability during storage and processing, preventing agglomeration and maintaining uniform dispersion in slurries or composites.
Perovskite Structure Stability: Retains its ABO?-type crystal structure under operational conditions (up to 800??C in oxidizing atmospheres), ensuring long-term durability in high-temperature applications.
Excellent Oxygen Ion Conductivity: Cobalt-rich composition promotes oxygen vacancy formation, enabling efficient oxygen transport??critical for SOFC cathode performance and oxygen separation membranes.
Core Applications
Solid Oxide Fuel Cells (SOFCs)
LSC641 is a benchmark cathode material for intermediate-temperature SOFCs (IT-SOFCs):

Cathode Layers: Enables high ORR activity at 600?C800??C, reducing polarization resistance and improving fuel cell efficiency.
Composite Electrodes: Compatible with electrolytes like YSZ (yttria-stabilized zirconia) or GDC (gadolinium-doped ceria), forming robust interfaces for enhanced performance.
Oxygen Separation Membranes
Oxygen Permeation: Facilitates selective oxygen transport through dense membranes, suitable for industrial gas purification (e.g., oxygen enrichment, syngas production).
Heterogeneous Catalysis
Oxidation Reactions: Catalyzes reactions such as CO oxidation, methane reforming, and volatile organic compound (VOC) degradation, leveraging its high surface area and redox-active cobalt sites.
