resistivity of A2Zr2O7is almost independent of the change in oxygen partial pressure. These properties are superior to the classical spinel-type or perovskite-type NTC thermistor, providing valuable information to explore new NTC thermistor for high-temperature applications....

In particular, several zirconate pyrochlores show low thermal conductivities and high thermal stabilities. Among them, lanthanum zirconate La2Zr2O7 (LZ) is phase-stable to its melting point. At the same time, it displays a lower thermal conductivity (1.56 Wm−1 K−1, bulk material) and a...
