因此，它们可应用于各种电气和热过程，其中包括固体氧化物燃料电池[4-6]、放射性废物处理[7]、航天器发动机[8-11]和催化剂。在1473K[12，13]下，Gd/Zr的热导率为1.91W m−1 K−1，热膨胀系数约为11.0×10−6 K−1，随Gd/Zr比[3，14]的变化而变化。此外，它还可以在1823K以下保持相稳定，比YSZ的相变点高出约300K，并且对CaO-MgO-Al_2O_3-SiO_2(CMAS)具有良好的耐化学性[9，15-20]。
Therefore, they could be applied in various electrical and thermal processes, including amongst others, Solid Oxide Fuel Cells (SOFCs)[4–6], radioactive waste processing [7], spacecraft engines [8–11], and catalysts. Gadolinium zirconate (GZ) has low thermal conductivity of 1.91 W m− 1 K− 1 and excellent thermal expansion coefficient of about 11.0× 10− 6 K− 1 at 1473 K [12, 13], which vary with the composition of Gd/Zr ratio [3, 14]. Besides, it can maintain phase stability below 1823 K, which is about 300 K higher than the phase transition point of YSZ, and has excellent chemical resistance to CaO-MgO-Al2O3-SiO2 (CMAS)[9, 15–20].
