Xenotime‐Type Rare‐Earth Orthophosphates REPO4 for Use as High‐Temperature Environmental Barrier Coatings

Journal of the American Ceramic Society, Volume 109, Issue 9, September 2026.
Can we make a more inexpensive and greener coating using naturally forming minerals? Xenotime mineral composition was determined to be (Y0.80Gd0.04Dy0.07Er0.05Yb0.04)PO4. Preliminary studies into REPO4 species showed compatable CTE match with SiC, formation of a multilayer reaction product that improves CMAS resistance, and parabolic growth rates ...

Wetting and spreading behaviour of molten CMAS towards thermal barrier coatings and its influencing factors

Results in Physics, 2021
Thermal barrier coatings (TBCs) are inevitably subject to corrosion caused by molten calcium-magnesium-alumino-silicate (CMAS), which leads to severe degradation in the properties of the coatings.

Corrosion behavior of Gd2Zr2O7 thermal barrier coatings under Fe-containing environmental sediment attack

Journal of Advanced Ceramics
Environmental sediments mainly consisting of CaO–MgO–Al2O3–SiO2 (CMAS) corrosion are a serious threat to thermal barrier coatings (TBCs), in which Fe element is usually ignored. Gd2Zr2O7 TBCs are famous for their excellent CMAS resistance. In this study,
