Thermal corrosion behavior and mechanism of (Gd0.9Yb0.1)2Zr2O7-GdTaO4 composite ceramic in Na2SO4 + V2O5 molten salt

Key Points

• Thermal corrosion behavior significantly alters under Na2SO4 + V2O5 conditions, prompting a shift in stability.
• Key evidence indicates that the corrosion rate increases when exposed to molten salts, suggesting degradation risks.
• Analysis of thermal corrosion utilizes a composite ceramic consisting of (Gd0.9Yb0.1)2Zr2O7 and GdTaO4, highlighting its structural integrity.
• Supports the need for further investigations into composite ceramics in high-temperature applications involving corrosive environments.
