Abstract

Fe₃O₄ nanoparticles were successfully prepared via chemical co-precipitation method. The effect of pH value, Fe³⁺/Fe²⁺ mole ratio and cation concentration on the phase structure, size and magnetic properties of the synthesized Fe₃O₄ nanoparticles was systematically studied. It was shown that uniform Fe₃O₄ nanoparticles with average diameter of c.a. 12 nm could be synthesized with controlled experimental parameters. The influence of pH value and surface surfactant coating on the dispersibility and stability of water-based Fe₃O₄ magnetic fluid was also studied. Water-based magnetic fluid of Fe₃O₄ nanoparticles coated with sodium oleate by chemical bonding can be successfully prepared with high stability.
