We deal with the preparation of NiMgZnFeIII−SO4 layered double hydroxides(LDHs)with the layered precursor method and introduce excessive ZnO into the NiMgZnFeIII−SO4 LDHs to produce NixMgyZn1−x-yFe_(2)O_(4) ferrites that contain massive ZnO.Then the NixMgyZn1−x-yFe_(2)O_(4) ferrites are treated with NaOH solution to remove ZnO to produce the porous NixMgyZn1−x-yFe_(2)O_(4) magnetic material:when y=0,porous NiZnFe_(2)O_(4) ferrite magnetic materials are obtained;when y≠0,porous NiMgZnFe_(2)O_(4) ferrite magnetic materials are obtained.From analyses of these two ferrites,their pore−forming mechanism and comparison of their properties before and after they undergo the alkali treatment,we find that after being treated by the NaOH solution,NiZnFe_(2)O_(4)/NiMgZnFe_(2)O_(4) have better uniform-structure pores,which will greatly expand their pore volume,widen their application scope and improve their magnetic properties.
