Results are presented for initial characterization of physical properties, microstructure, and phase structure of partially stabilized HfO/sub 2/ single crystals. These results, for crystals prepared by skull melting, are compared with those for ZrO/sub 2/ single crystals of similar composition and for fully stabilized ZrO/sub 2/ and HfO/sub 2/ single crystals. The observed microstructures and mechanical properties suggest that partially stabilized HfO/sub 2/ crystals may be useful high temperature structural ceramics.
