摘要：

The influence of the main reaction parameters (temperature, pH and concentration) in the oxidative hydrolysis of iron(II) sulphate in an acid medium on the properties of the obtained alpha-Fe2O3 and its applicability in ferrite production has been studied. The addition of manganese(II) ions catalyses the process in the homogeneous phase, probably by activation of oxygen. The obtained results are discussed within the framework of the assumed reaction mechanism, which includes an homogeneous reaction and a heterogeneous one with the participation of the oxidative hydrolysis product alpha-FeOOH.
