Abstract

Способ получения оксида железа (III), используемого для производства ферритов, из солянокислого травильного раствора, включающий очистку его от кремния и последующую термообработку очищенного раствора с получением целевого продукта в присутствии кислородсодержащего газа, отличающийся тем, что, с целью повышения удельной поверхности продукта, степени его чистоты и упрощения процесса, очистку раствора осуществляют путем введения в него фторида или бифторида аммония в количестве 0,7 - 1,2 от стехиометрии в пересчете на SiO, а термообработку проводят при 350 - 700C.The method of producing iron (III) oxide used for the production of ferrites from pickling hydrochloric acid solution, including its purification from silicon and subsequent heat treatment of the purified solution to obtain the target product in the presence of oxygen-containing gas, characterized in its purity and simplification of the process, cleaning the solution is carried out by introducing into it fluoride or ammonium bifluoride in the amount of 0.7 - 1.2 from stoichiometry in terms of SiO, and heat treatment is about drive at 350 - 700C.
