Rayleigh wing broadening (quasielastic scattering) was found at high temperatures (650--1500 K) in cubic zirconia single-crystal ZrO/sub 2/ fully stabilized with Y/sub 2/O/sub 3/; however, broadening was not observed in the two-phased cubic plus tetragonal zirconia crystals. We believe this can be interpreted as a disorder-order transition as the configuration goes from single-phase cubic-to-cubic plus tetragonal structure with less addition of Y/sub 2/O/sub 3/. Theoretical agreements were achieved by utilizing ''rigid ion model'' and ''decay model'' calculations.
