    Abstract

    The thermal diffusivity, κ, and conductivity, λ, of Ca-doped stabilized zirconia were simultaneously measured up to 5.3 GPa and 700 K employing the pulse transient method. From κ and λ, heat capacity, C, was also derived. The temperature dependences of κ and λ at 5.3 GPa were found to be very small, and may be due to oxygen ion conduction. The present data are especially useful for designing a high-pressure cell in a Kawai-type apparatus, where Ca-doped stabilized zirconia has been frequently used as thermal insulator around a heater.
