La 2 Ce 2 O 7 (LC) is a new promising thermal barrier coating (TBC) material for high-temperature applications. However, the sudden decrease of thermal expansion coefficient (TEC) at ∼623 K limits its application. In this study, the plasma-sprayed La 2 Ce 1.7 Ta 0.3 O 7.15 (LCT) coating was developed by partial substitution of Ce 4+ in LC with Ta 5+ . LCT coating shows lower thermal conductivity between 298 K and 1273 K (0.54–0.71 W/(m·K)) than LC coating (0.65–0.85 W/(m·K)) and the traditional yttria partially stabilized zirconia (YSZ) co...
