Abstract
The surface cation densities of FexCr2 - xO3 solid solutions were determined for x = 0.5, 1, and 1.5 using Auger Electron Spectroscopy on samples that had been equilibrated in air at 798 or 973 K. Cr(VI) was found to be present on the surface by iodometric titration. The results indicated that the Cr(VI) Cr(III) ratio was constant, independent of composition. Compared to the bulk densities, Fe was found to be enriched on the surface for x = 0.5 and 1, but depleted for x = 1.5.
