Manufacturing Solution for Producing Cobalt-ferrite Films

An extraction-pyrolytic technique and its usage for obtaining pure products from secondary manufacturing solutions are considered in this paper. Nanostructure ferrite thin films were prepared using the extraction-pyrolytic technique. It was shown that the extraction from modeling liquid of waste solution allows obtaining the pure single phase product. Fe2CoO4 magnetic films with grain sizes 18-20 nm were obtained by cycling pyrolysis of wet films deposited by the spin coating technique.
