METHOD OF PRODUCING IRON-BASED COMPLEX METAL OXIDE Russian patent published in 2011 - IPC C01B13/18 C01G49/02 

FIELD: chemistry.

SUBSTANCE: invention relates to chemical industry, specifically to production of magnetrostrictive materials based on composite metal oxides, particularly ferrites. The method of producing the iron-based metal oxide involves thermal processing of inorganic hydrated salts of corresponding metals in a water vapour atmosphere. The inorganic hydrated salts used are powdered halides of corresponding metals, and thermal processing is carried out in a current of air and water vapour, while feeding the mixture at a rate of V=^{0.1 volume of reaction space}/min. The obtained complex metal oxide is among a group comprising oxides of cobalt, nickel and copper.

EFFECT: method is simple and reliable, and also ensures high purity of the end product.
