Abstract:(Fe, AI)203 solid solution was prepared by hot press sintering Fe2O3andAI2O3powdersthat had been high energy ball milled at room temperature. Partial reduction of the as-prepared solid solution in hydrogen produced the separated iron particles dispersed on an Al203 substrate. XRD and TEM were used to characterize the partially reduced sample and its phase composition, and the dispersion of the reduced iron on an alumina substrate was also examined.
Key words:single phase (Fe, AI)203 solid solution; XRD; partial selective reduction
