The Formation of the Oxidized Fe3O4–Fe2TiO4 Solid Solution by the Air Oxidation of the Aqueous Suspension

The oxidized Fe3O4–Fe2TiO4 solid solution with the spinel type structure was synthesized by means of ferrite methods at pH 9.0 and 65 °C. When the solid solution thus obtained was heated at 200 or 300 °C in air for 20 h, it was completely oxidized to form a ferromagnetic product, which retained the spinel type structure for Ti/Fetotal ratios from 0 to 0.5.
