LSCF:GDC 1:1 Cathode Slurry 1kg SOC Grade ATOMFAIR®

Composite Cathode Slurry (LSCF:GDC=1:1), 1 kg | ATOMFAIR

Product Type: SOC composite cathode slurry

Research-grade laboratory product

Product Overview

This ATOMFAIR® slurry is a composite blend of LSCF and GDC in a 1:1 weight ratio, with 60–75 wt.% solids, fineness <5 μm, and viscosity in the 2200–3000 mPa·s range. It serves as a high-performance cathode functional layer, where the LSCF phase provides excellent oxygen reduction activity and the GDC phase extends the triple-phase boundary area while inhibiting Sr segregation. The paste is engineered for co-sintering with both zirconia and ceria-based electrolytes, offering robust adhesion and superior electrochemical performance in intermediate-temperature cells.

Performance Features

Extended TPB region: GDC addition substantially increases active reaction sites.
High oxygen exchange rate: LSCF ensures rapid surface and bulk oxygen transport.
Suppressed Sr segregation: GDC stabilizes the perovskite structure, prolonging lifetime.
Good co-firing compatibility: Suitable for both YSZ and GDC electrolyte configurations.

This document outlines the environmental and processing constraints for the safe and effective use of the ATOMFAIR LSCF:GDC (1:1) composite cathode slurry. Adherence to these constraints is critical to prevent solvent evaporation, viscosity drift, and contamination during storage and application.

Storage Environment: Store the slurry in a cool, dry environment to prevent solvent evaporation and viscosity drift.
Container Sealing: Keep the container tightly sealed when not in use to avoid contamination and solvent loss.
Co-firing Compatibility: The slurry is engineered for co-sintering with both zirconia and ceria-based electrolytes, requiring adherence to specified sintering profiles.

FAQ

What is the optimal solids content range for this LSCF:GDC composite cathode slurry and how does it affect screen-printing performance?

The slurry has a solids content of 60–75 wt.%, which directly influences its viscosity of 2200–3000 mPa·s and fineness below 5 μm. This range ensures good screen-printability and uniform layer deposition for cathode functional layers in solid oxide cells.

Can this LSCF:GDC composite cathode slurry be co-sintered with both YSZ and GDC electrolytes?

Yes, the slurry is engineered for co-sintering with both zirconia (YSZ) and ceria-based (GDC) electrolytes. The GDC phase in the composite also suppresses Sr segregation and extends the triple-phase boundary region, enhancing compatibility and electrochemical performance in intermediate-temperature cells.

What storage conditions are required to prevent viscosity drift and solvent evaporation for this slurry?

Store the slurry in a cool, dry environment and keep containers tightly sealed when not in use. This prevents solvent evaporation, viscosity drift, and contamination, ensuring consistent screen-printing properties and performance.

Assessment

This composite cathode slurry (LSCF:GDC=1:1) offers a balanced combination of high oxygen reduction activity from LSCF and extended triple-phase boundary from GDC, with suppressed Sr segregation for improved durability. However, it requires careful storage and screen-printing process control to maintain performance.

Positive

Extended Triple-Phase Boundary Area: GDC addition substantially increases active reaction sites, enhancing oxygen reduction activity in the cathode functional layer.
Suppressed Sr Segregation: The GDC phase stabilizes the perovskite structure, inhibiting strontium segregation and prolonging operational lifetime.

Trade-offs

Strict Storage Requirements: The slurry must be stored in a cool, dry environment with containers tightly sealed to prevent solvent evaporation, viscosity drift, and contamination.
Screen-Printing Process Sensitivity: The viscosity range of 2200–3000 mPa·s and fineness <5 μm require precise screen-printing parameters and co-sintering profile optimization to achieve uniform film quality.
