An investigation of the effect of crystal anisotropy on the strength of oxides is described. Solid solutions of various materials in rutile TiO2 and zincite ZnO were prepared and the thermal expansion properties were measured in an attempt to find compositions with reduced anisotropy. Bodies composed of 72 Al2O3-28 Cr2O3 were prepared by reactive hot pressing. Preliminary evidence of a strengthening effect compared with pure Al2O3 is presented.
