Neutron powder diffraction has been used to measure the temperature factors of both the cation and the anion atoms in 10mol% Y 2 O 3 –ZrO 2 over the temperature range 15 to 1323 K. The Housley–Hess approach has been used to determine the static disorder term of the temperature factors for both the Zr/Y and O atoms. The static contribution was determined to be 1.04 (6) Å 2 for Zr/Y and 2.2 (1) Å 2 for O. From these results, a Debye temperature of 527 (20) K was calculated for this sample.
