Thermal Conductivity of Two Compositions of Yttria-Stabilized Zirconia
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-sided 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 -1 K -1 and 2.3 Wm -1 K -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.
