STRENGTHENING OXIDES BY REDUCTION OF CRYSTAL ANISOTROPY

Abstract

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.
