This document outlines the technical constraints for handling and processing the ATOMFAIR Lanthanum Strontium Cobalt Oxide Powder II. The powder requires controlled storage to maintain its flowability and avoid contamination.
- Storage Environment: Store the powder in a dry, cool environment to prevent moisture uptake and preserve powder flowability.
- Container Sealing: Keep the container tightly sealed when not in use to prevent contamination and maintain powder quality.
- High-Temperature Reactivity: Minimize exposure to high temperatures during processing to avoid unwanted solid-state reactions, as the low specific surface area limits interfacial reaction.
- Process Compatibility: Use dry mixing techniques and large-area coating processes to leverage the free-flowing properties of the powder.
- Application Fit: Confirm that the application requires open porous structures for gas diffusion and mechanical reinforcement before using this powder.
Why use coarse LSC powder (20–45 μm) instead of finer particles for SOC electrode layers?
Coarse particles create an open porous scaffold that enhances gas diffusion and mechanical reinforcement in supporting or backbone electrode layers. The low specific surface area (0.2–0.6 m²/g) also minimizes unwanted high-temperature solid-state reactions with adjacent components, a critical advantage over finer powders.
Is this LSC powder suitable for both SOFC and SOEC electrode applications?
Yes, it is designed for both solid oxide fuel cell (SOFC) and solid oxide electrolysis cell (SOEC) electrode architectures. The composition La₀.₈Sr₀.₂CoO₃₋δ and coarse morphology are optimized for supporting/backbone layers that require open pore structures and thermal expansion matching in both modes.
What storage conditions are required to maintain the powder's flowability and low moisture content?
Store in a dry, cool environment and keep containers tightly sealed to prevent moisture uptake and contamination. The powder is specified at <1 wt.% moisture, and proper storage preserves its free-flowing properties for dry mixing and large-area coating processes.
This Lanthanum Strontium Cobalt Oxide Powder II (D50 20-45 μm) is engineered for SOC supporting electrodes, where its coarse morphology and low surface area provide structural integrity and gas permeability while minimizing interfacial reactions at high temperatures.
Positive
- Open porous scaffold structure: Coarse particles (D50 20–45 μm) create open pores for efficient gas diffusion and mechanical reinforcement in SOC electrode supporting layers.
- Minimized high-temperature reactions: Low specific surface area (0.2–0.6 m²/g) reduces unwanted solid-state reactions at elevated temperatures, enhancing long-term stability.
Trade-offs
- Moisture-sensitive handling required: Powder must be stored in a dry, cool environment and containers kept tightly sealed to prevent moisture absorption and maintain flowability.
- Limited to backbone layer applications: Coarse particle size and low surface area restrict catalytic activity, constraining use to supporting/backbone layers rather than active electrode layers.
