Abstract

The aim of this paper is to synthesize α-(Fe, Al)2O3 solid solutions from precursors prepared by the sol–gel method. The powders were characterized by X-ray diffraction, particle size analysis and TGA-DSC. The results indicated that the precursor prepared by sol–gel method will translate into α-(Fe, Al)2O3 solid solutions after calcined at 1300 °C for 3 h, with the average grain size of 14 μm. And Fe2O3 reduced the temperature of the γ-Al2O to α-Al2O3 phase transition from 1,300 to 850 °C.
