通过模型实验研究了xZrO_2·(1−x)GdO_(1.5)与α-Al_2O_3接触时的热稳定性。为避免有害反应，建议实际热障涂层中GdO1.5的含量不超过x=0.15，x=0.15是ZrO2-GdO1.5系统陶瓷中导热系数最低的组份之一。
Model experiments were performed to elucidate the thermal stability of xZrO2·(1−x)GdO1.5in contact with α-Al2O3, in powder forms. To avoid detrimental reactions, it is recommended that the GdO1.5content in actual thermal barrier coatings not exceed x=0.15, a composition with one of the lowest thermal conductivities of ceramics in the ZrO2–GdO1.5system.
