The hemispherical total emissivity of partially stabilized zirconia has bee
n obtained by a spectral analysis of the normal emission spectra between 40
0-850 K. Thermal conductivity was evaluated with this emissivity and temper
ature gradient in the sample. Effects of the scattering of the radiation in
a ceramic sample are also investigated. In addition, specific heat capacit
y was measured by thermal radiation calorimetry. Current results are compar
ed with those reported for tetragonal zirconia with the same yttria content
and for monoclinic phase.
