Method for producing iron oxide magnetic particles, and iron oxide magnetic particles formed therefrom

Abstract

The present disclosure provides: a method for producing iron oxide magnetic particles, the method including synthesizing an iron precursor by mixing an iron salt, at least one fatty acid salt selected from the group consisting of fatty acid salts including fatty acid salts having 4 to 25 carbon atoms, and at least one alcohol selected from the group consisting of alcohols having 1 to 5 carbon atoms, and then heating and washing the mixture to form an iron fatty acid complex, synthesizing iron oxide particles containing MX1n by mixing the synthesized iron precursor, MX1n, and at least one aliphatic alcohol selected from the group consisting of aliphatic alcohols having 6 to 25 carbon atoms, and heating the mixture, and forming iron oxide magnetic particles containing the synthesized iron oxide particles and MX2n by mixing the synthesized iron oxide particles into a solution containing AX2n, and replacing the X1n and X2n, and iron oxide magnetic particles formed from the method.
