Abstract
There is disclosed a method for forming a ferrite coatings on a substrate, which comprises: PA0 (a) bringing a substrate into contact with water or an aqueous solution, and PA0 (b) adding a ferrous ion solution, an oxidizer solution and a pH controller so that pH and an oxidation-reduction potential may be included within the range specified by A (6, -440 mV), B (6, -130 mV), C (11, -430 mV) and D (11, -740 mV) in a pH - oxidation-reduction potential graph.
