摘要：
The influence of Fe on the microstructure of Al2O3-MgO-Fe2O3 spinel is described in this work. Heating a mixture of initial oxides in an electric furnace at 1400 degrees C for 15 hrs produced the spinel. A ternary diagram for concentration ranges: Al2O3 (5-75 mol%), MgO (10-80 mol%), and Fe2O3 (3-70 mol%) summarize the constitution of this spinel. Amount, composition and weight ratios of each phase were determined by X-rays powder diffraction. Microstructure of specimens was characterized by scanning electronic microscopy and Xray spectrometry. Distribution, size, shape of phases and pores were examined. Hardness measurements of spinel completed this study.
