Store the powder in a dry environment and keep containers tightly sealed to prevent moisture uptake and contamination. The powder is intended for high-temperature SOFC cathode fabrication via screen-printing or tape-casting, requiring good adhesion to zirconia-based electrolytes and stability under oxidizing atmospheres.
- Storage Requirement: Store in a dry environment to prevent moisture uptake, which can degrade performance.
- Container Sealing: Keep containers tightly sealed when not in use to avoid contamination and moisture absorption.
- Processing Compatibility: The powder is designed for screen-printing or tape-casting applications, requiring appropriate slurry preparation and coating techniques.
- Electrolyte Adhesion: Formulates good interfacial bonding with YSZ and 8YSZ electrolytes, ensuring adhesion during sintering.
- Thermal Cycling: Maintains structural integrity across repeated thermal cycles, but should be handled with care to avoid contamination.
How does the D50 particle size range of 0.3–0.6 μm affect screen-printing or tape-casting performance for SOFC cathodes?
The D50 of 0.3–0.6 μm, combined with a specific surface area of 6–10 m²/g and uniform spherical-like morphology, is specifically engineered to produce defect-free, well-adhered coating layers via screen-printing or tape-casting. This particle size range balances packing density and reactivity without causing excessive sintering or cracking during high-temperature operation.
Is this LSM powder compatible with YSZ or 8YSZ electrolytes for high-temperature SOFC applications?
Yes, the powder is designed for strong interfacial bonding with YSZ and 8YSZ electrolytes. The nominal composition (La₀.₇₅Sr₀.₂₅)₀.₉₅MnO₃₋δ is a standard cathode material that maintains robust adhesion and electrochemical performance under oxidizing atmospheres at SOFC operating temperatures.
What are the storage and handling requirements for this LSM powder to prevent performance degradation?
Store the powder in a dry environment and keep containers tightly sealed when not in use to prevent moisture uptake, as the specified moisture content is <1 wt.%. The powder is non-granulated and as-synthesized, so it is sensitive to humidity and contamination. Professional research-grade packaging is provided to maintain integrity during storage and transport.
The ATOMFAIR Lanthanum Strontium Manganite Powder (AF-LSM-PD) with D50 0.3–0.6 μm offers a well-established cathode material for high-temperature SOFCs, balancing thermal stability, electrolyte adhesion, and controlled particle morphology for screen-printing and tape-casting—but requires strict moisture control and high-temperature infrastructure for reliable operation.
Positive
- Long-term high-temperature durability: Proven stability under SOFC operating conditions, maintaining structural integrity across repeated thermal cycles for extended cathode lifespan.
- Strong YSZ electrolyte adhesion: Forms excellent interfacial bonding with YSZ and 8YSZ electrolytes, enabling defect-free coatings via screen-printing or tape-casting.
Trade-offs
- Moisture-sensitive storage required: Moisture content <1 wt.% necessitates storage in a dry environment with tightly sealed containers to prevent performance degradation.
- High-temperature processing infrastructure: Designed for SOFC applications requiring sustained high-temperature operation, demanding specialized furnace and thermal management equipment.
