Abstract:

Samples of cubic zirconium oxide contained 2.5at - 40af ferric iron were prepared by codecomposition of the nitrates. X-ray powder diffraction analysis and magnetic measurements indicated that alpha iron nitrate and ZRO2 form a solid solution up to 25at FeZr in the product. At this point, the solubility limit of alpha-Fe2O3 in ZrO2 is exceeded. The reduction of cubic zirconia samples containing 2.5at - 20at FeIII leads to the stabilization of iron II in the zirconia lattice. Reduction to metallic iron occurs at much higher temperatures than the reduction of bulk alpha-Fe2O3. Reprints
