FIELD: chemistry.
SUBSTANCE: to obtain highly dispersed magnetically ordered iron (III) oxide, the γ-Fe2O3 magnetic phase is deposited in the presence of air for 24 hours at room temperature and atmospheric pressure from aqueous alkaline solutions iron (II) salts, cyclodextrins (CD) and a hypophosphorous acid salt, taken in molar ratio CD: Fe2+: NaH2PO2=1:100:100.
EFFECT: invention enables to obtain maghemite in highly dispersed state at room temperature at atmospheric pressure with increase in purity thereof.
