Abstract
The thermal conductivities of two different compositions of yttria-stabilized zirconia have been measured using an absolute, steady-state method. The measurements were made in a one-dised guarded-hot-plate apparatus from 130 C to 950 C. one material has a predominantly tetragonal phase composition, and the other is predominantly cubic. The average measured values of thermal conductivity at 950 C for the two compositions of yttria-stabilized zirconia are 2.8 Wm-1K-1 and 2.3 Wm-1K-1, respectively. The thermal conductivities of both compositions are nearly independent of temperature. The results show that both materials show promise as potential candidates for standard reference materials for high-temperature thermal conductivity.
