Results are presented for the measured single‐crystal elastic constants of yttria‐stabilized zirconia, for yttria contents of 1.7 to 20 mol%. The results cover a range of materials which vary from a mixture of monoclinic, tetragonal, and cubic to those which are fully cubic. These single‐crystal measurements are used to calculate the bounds on the elastic moduli for polycrystalline materials. Comments are made on the elastic anisotropy of zirconia relative to a number of other single‐crystal ceramics, with graphical comparisons of the anisotropy of Young's moduli of these ceramics.
