METHOD OF PRODUCING MAGNETOACTIVE COMPOUND Russian patent published in 2016 - IPC C01G49/08 H01F1/01

Abstract RU 2576436 C1

FIELD: chemistry.

SUBSTANCE: magnetoactive compound is obtained via condensation from iron (II) salt solutions and an oxidising agent while mixing and adding an alkaline agent. The iron (II) salt used is iron (II) sulphate heptahydrate. The oxidising agent used is a chromium (VI) salt solution - potassium chromate or potassium bichromate.

EFFECT: invention enables to obtain a magnetoactive compound without releasing toxic nitrogen oxides.
