Abstract

The phase stability of lanthanum cerium oxide (La2Ce2O7), which is stable up to 1400 °C, and the thermal expansion coefficient of La2Ce2O7 doped with Ta2O5 or WO3 were studied. The thermal expansion coefficient of La2Ce2O7 below 400 °C was increased by adding more CeO2 or doping with either Ta2O5 or WO3.
