Enhancement of thermal properties of ytterbium-cerium oxide by zirconium doping for thermal barrier coatings

Rare-earth cerium oxides (RE2Ce2O7, RE = rare-earth elements) are proposed as promising thermal barrier coatings (TBCs) material due to large thermal expansion coefficient (TEC), phase stability and a comparable thermal cycling life to Yttria-Stabilized Zirconia (YSZ). However, the thermal conductivity of RE2Ce2O7 is relatively higher than that of both YSZ and rare-earth zirconates. Here, we report an effective method of reducing the thermal...
