Recently, a research team from the Faculty of Materials Science and Technology at Kunming University of Science and Technology, comprising Guiyu Xue, Lin Chen, Luyang Zhang, Jiankun Wang, and Jing Feng, has made significant progress in the study of ABO₄-type oxides as candidates for thermal/environmental barrier coatings (T/EBCs). Their findings are published in a study titled "Typical structures and thermal expansion coefficients of ABO₄-type (A=Ga, In, Cr; B=Nb, Ta) oxides as EBC candidates" (https://doi.org/10.1016/j.exm.2024.12.002) on Extreme Materials (ISSN 3050-628X).

Highlight of research:

1. This work screens ABO₄-type oxides as T/EBCs for different substrates.

2. Changing the A-site ionic radius is a good way to regulate TECs of ABO₄-type oxides.

3. AlNbO₄, InNbO₄, and GaTaO₄ are chosen as EBCs for C-, SiC-, and Al₂O₃-based substrates, respectively.
