LSGM Lanthanum Gallate Powder D50 0.4-0.7μm ATOMFAIR®

LSGM Lanthanum Strontium Gallium Magnesium Oxide Powder, D50 0.4-0.7 μm, 1 kg | ATOMFAIR

Product Type: SOC electrolyte material powder

Research-grade laboratory product

Product Overview

The ATOMFAIR® Lanthanum Strontium Gallium Magnesium Oxide Powder is a gallate-based perovskite electrolyte with the composition La₀.₈Sr₀.₂Ga₀.₈Mg₀.₂O₃₋δ, recognized for its high oxygen-ion conductivity over a wide oxygen partial pressure range, without significant electronic leakage. It has a D50 of 0.4–0.7 μm, a specific surface area of 6–10 m²/g, and moisture <1 wt.%. This material is particularly attractive for intermediate-temperature SOFCs due to its superior conductivity at 500–800 °C, and it shows good compatibility with both high-performance cathodes and anodes, enabling efficient and reliable cell designs.

Performance Features

Wide working window: Maintains high conductivity across a broad range of pO₂ conditions.
Negligible electronic leakage: Purely ionic conduction ensures high faradaic efficiency.
High conductivity at moderate temperature: Outperforms YSZ below 800 °C.
Good electrode compatibility: Works effectively with LSCF, LSM, and nickel-based anodes.

FAQ

How does LSGM (La₀.₈Sr₀.₂Ga₀.₈Mg₀.₂O₃₋δ) powder compare to YSZ for use as an electrolyte in intermediate-temperature SOFCs?

LSGM offers superior oxygen-ion conductivity compared to YSZ at temperatures below 800 °C, making it particularly attractive for intermediate-temperature SOFCs operating at 500–800 °C. It maintains high conductivity across a wide oxygen partial pressure range with negligible electronic leakage, ensuring high faradaic efficiency. The source explicitly states it 'outperforms YSZ below 800 °C.'

Which cathode and anode materials are compatible with this LSGM electrolyte powder?

This LSGM powder shows good compatibility with high-performance cathodes such as LSCF and LSM, as well as nickel-based anodes. This compatibility enables efficient and reliable cell designs for solid oxide cells.

What storage conditions are required to maintain the integrity of LSGM powder with D50 0.4–0.7 μm?

The powder must be stored in a dry environment with containers tightly sealed when not in use to prevent moisture uptake and contamination. The specification lists moisture content below 1 wt.%, and improper storage can compromise the material's performance.

Assessment

This LSGM electrolyte powder (La0.8Sr0.2Ga0.8Mg0.2O3-δ) provides high purely ionic conductivity with negligible electronic leakage across a wide pO2 range, making it suitable for 500–800 °C SOC electrolytes. Its D50 of 0.4–0.7 μm and 6–10 m²/g surface area support electrode integration, but strict dry storage is required due to hygroscopic behavior.

Positive

High purely ionic conductivity: Exhibits high oxygen-ion conductivity across a broad pO2 range with negligible electronic leakage, enabling high faradaic efficiency in intermediate-temperature SOFC electrolytes (500–800 °C).
Good electrode compatibility: Compatible with high-performance cathodes (LSCF, LSM) and nickel-based anodes, simplifying cell design and integration for solid oxide cell applications.

Trade-offs

Moisture sensitivity: As a hygroscopic powder (<1 wt.% moisture as-received), it requires storage in a dry environment with tightly sealed containers to prevent moisture uptake and contamination during handling and storage.
