ABSTRACT:
A process wherein a magnetic iron precursor component characterized as the mineral ilmenite, FeTiO.sub.3, particularly the natural mineral ilmenite, FeTiO.sub.3, is incorporated within a refractory inorganic oxide particulate mass, notably alumina, silica, silica-alumina, aluminosilicate or precursor thereof, which serves as a matrix. The mineral can be prereduced and then formed into a composite, or said mineral can be dispersed as an inclusion, or inclusions, and the particulate composite mass then treated in a reducing atmosphere to form oriented, laminar layers of reduced iron metal intimately dispersed throughout said particulate composite mass.
