Advanced Materials, 2003•Wiley Online LibraryLa2Ce2O7 is proposed as a new material for thermal barrier coating that has a higher
thermal expansion coefficient and a lower thermal conductivity than traditional coating
materials. After long‐term annealing at 1400° C, the crystal structure of La2Ce2O7 was
maintained (see Figure). Below 300° C, thermal contraction occurs, and the material has a
comparable thermal cycling life to yttria‐stabilized zirconia coatings.
