Polarity‐induced grain growth of gadolinium‐doped ceria under field‐assisted sintering technology/spark plasma sintering (FAST/SPS) conditions

This study aims to understand the effect of the electrical field on microstructure evolution during field‐assisted sintering or spark plasma sintering (FAST/SPS) of 10 mol% gadolinium‐doped ceria (GDC) with experimental and numerical methods. The novelty of this study has been the observation of enh...
