The materials were developed by a liquid phase sintering process (700°C) from a compacted blend of high-purity powders of aluminum and hematite. The composites thus obtained were heat treated (500°C, 1 h). The structural features were studied by x-ray diffraction and Rietveld refinement, and the magnetic properties, by the VSM vibrating sample magnetism as well as light microscopy observations. We also noted that aluminum influences the magnetic and electrical properties (resistivity) of the composite materials in comparison with pure hematite. The presence of the ordered B2–FeAl phase, even in a very small quantity, shows that it is possible to synthesize the FeAl phase by thermite reaction, which constitutes a new fact for this type of composite materials, given its impact on the magnetic and thermal properties. Particular attention will be paid to the composite containing 40% hematite as it has interesting physical characteristics, especially magnetic because of the formation of the FeAl ordered compound.
