Abstract
The RE2O3 (RE = La, Yb, Ce, Gd) co-doped Y2O3 stabilized ZrO2 (RE-YSZ) powders were prepared by a sol–gel method. To study the effect of RE2O3 addition on phase and structure formations, crystal growth and thermal conductivity, the investigations proposed in this paper cover X-ray diffraction, scanning electron microscopy, transmission electron microscopy, and laser thermal conductivity meter. The results indicate that RE2O3 (RE = La, Yb, Ce, Gd) co-doped Y2O3 stabilized ZrO2 powder could improve phase stability and reduce thermal conductivity. In addition, crystal growth occurs due to different growth mechanisms at low and high temperature; the activation energy at low temperature is obviously lower than that at high temperature. Considering the comprehensive performance, it can be concluded that Yb-yttrium oxide-stabilized zirconia powder is a good thermal barrier coating.
