LSM (Lanthanum Strontium Manganite) Powder
Full Product Datasheet
Key Properties & Advantages
- Controlled Particle Size (0.3–0.6 μm): Ensures uniform packing in cathode layers, balancing porosity for gas diffusion and active contact area for oxygen reduction reactions (ORR) during high-temperature cycling.
- Optimized Surface Properties: Provides sufficient active sites for ORR while resisting excessive sintering at 800–1000°C, supporting long-term SOFC stability.
- Low Moisture Content (<1 wt.%): Prevents agglomeration and enables uniform dispersion in slurries and composite electrodes (e.g., with YSZ).
- Exceptional Thermal Stability: Maintains perovskite structure and electrical conductivity at elevated temperatures, better than many cobalt-based oxides.
- Chemical Compatibility with YSZ: Forms stable interfaces with YSZ electrolytes, minimizing interfacial resistance and unwanted phase reactions.
- High Electronic Conductivity: Strontium doping boosts p-type conductivity for efficient electron transport in cathodes.
Core Applications
High-Temperature Solid Oxide Fuel Cells (SOFCs)
- Cathode Layers: Provides stable ORR activity at 800–1000°C for conventional SOFC power generation systems.
- Composite Cathodes: Usually mixed 1:1 with YSZ to combine ionic conduction (YSZ) and electronic transport (LSM), lowering polarization resistance.
- Long-Life Stacks: Resists degradation over extended cycling, supporting SOFC lifetimes >10,000 hours for commercial use.
High-Temperature Sensors & Catalysis
- Oxygen Sensors: Used as a sensing electrode in zirconia-based O₂ sensors for industrial furnaces and exhaust monitoring.
- High-Temperature Catalysis: Suitable for methane reforming, NOₓ reduction, and other high-heat catalytic reactions.
