Thermal barrier coatings (TBCs) are widely used to protect and insulate hot-section metal components in gas-turbine engines. To enhance the efficiency of engines, higher operating temperatures are required, which can be realized by using TBCs with lower thermal conductivity. La2Mo2O9 is an attractive material for TBC since it exhibits significantly low thermal conductivity, namely 0.95 Wm-1K-1 at 1273 K. Elemental substitution is expected to reduce the thermal conductivity of La2Mo2O9 furthermore by phonon-defect scattering. In this study, we prepared Bi-substituted La2Mo2O9 by conventional solid state reaction. The effect of the Bi substitution on the thermal and mechanical properties of the La2Mo2O9 system was studied.
