In this paper, the hardness of single crystals of flux-grown, untwinned monoclinic zirconia is determined using Knoop and Vickers microindenters. Significant harness anisotropy existed on (100) and (110) faces, with a maximum Knoop hardness of [approximately] 8 GPa, although large variance was observed between different batches of crystals. Extensive deformation twining, primarily on (110), but also on (001), accompanied microindentation at all temperatures between room temperature and 800[degrees]C.
