Synthesis of magnetite nanoparticles by precipitation with forced mixing

Abstract

Synthesis of magnetite nanoparticles by precipitation with forced mixing is presented. Using this method it is easy to obtain a high product saturation degree and the constant pH value of the reaction system. The TEM and XRD measurments show that the average size of the product magnetite particles is less than 6.0 nm in the condition of [Fe2+]/[Fe3+] = 0.5. The magnetic properties of the samples are discussed.
