摘要：
In continuation of work on potentials for the design of high-performance thermal barrier coatings based on three-component ceramic materials containing rare-earth oxides, here we discuss the results of our study of the effects of components on the thermophysical properties of Gd2O3-ZrO2-HfO2 ceramics. Gadolinium oxide and hafnium oxide stabilize the thermal coefficient of linear expansion (TCLE) of ceramic samples in the three-component system Gd2O3-ZrO2-HfO2. Given that the gadolinium oxide and hafnium oxide are in equal amounts (10 to 15 mol %) and zirconia is an amount of at least 70 mol %, the TCLE (alpha(L)) of Gd2O3-ZrO2-HfO2 ceramics ranges from 7.4 x 10(-6) to 10.5 x 10(-6) with acceptable values of thermal conductivity (0.98-1.35 W/(m K)).
