Heat Capacity of Monoclinic Zirconia between 2.75 and 350 K

Abstract: We have measured the constant-pressure heat capacity C, of pure monoclinic ZrOz between 2.75 and 350 K. At low temperatures we find heat capacity in excess of the thermal acoustic phonon contribution, which we attribute to the ingress of low-lying optic mode vibrations. We have calculated the heat capacity at constant volume C, at the hightemperature end of our measurement range and used these values with the harmonic model to derive the moments of the phonon spectrum. Comparing the moments of the monoclinic p… Show more

“…They are also plotted in figure 1 together with the literature values of pure zirconia. (14,15) The Debye characteristic temperature D of pure zirconia and 7.76·10 −2 mole fraction yttria-stabilized zirconia was estimated from the measured heat capacity assuming three degrees of freedom per atom, and is shown in figure 2. As far as the present authors know, the heat capacity of pure zirconia has been reported by two other workers.…”
