Mixtures containing the desired weight ratios of α-Fe2O3 and γ-AlOOH were homogenized in the planetary mill, then pressed into tablets and heated up to 1200 °C. All samples were characterized by X-ray diffraction, Mössbauer spectroscopy, Field emission scanning electron microscopy and Energy dispersive X-ray analysis. Two types of solid solutions of general formula α-(AlxFe1-x)2O3 were found; one solid solution was closely related to α-Fe2O3 the other to α-Al2O3 The terminal solid solubility limits, r = 27.0 ± 0.5 mole ratio of α-Al2O3 in α-Fe2O3 and r = 9.0 ± 0.5 of α-Fe2O3 in α-Al2O3 were determined. The Mössbauer spectra showed a broadening of spectral lines and a decrease in the hyperfine magnetic field of α-Fe2O3 with incorporation of ...
