Abstract

The corrosion behavior of yttria-stabilized zirconia (YSZ) in molten salts is of great relevance for its application as thermal and environmental barrier coating in nuclear and renewable energy. The corrosion behavior of zirconia (ZrO₂) and 8 mol% YSZ (8YSZ) in LiF–NaF–KF (FLiNaK) salt at 900 °C for 250 and 500 h was studied. YSZ suffered of a higher weight loss compared to zirconia (for example, 5.84 wt% for 8YSZ compared to 4.04 wt% for ZrO₂ at 500 h) and underwent a phase transformation from tetragonal to monoclinic phase due to the loss of yttria, as confirmed by Raman spectroscopy.
