Abstract

A simple recipe for preparing a small quantity of magnetite nanaoparticles in aqueous suspension by coprecipitation is presented. The nanoparticles were characterized by X Ray Diffraction, by a nontypical Dynamic Light Scattering procedure and by Atomic Force Microscopy and the results are compared and discussed. The time variation of the refractive index of the aqueous nanofluid during aqueous dilution is presented and discussed in connection with aggregate formation..
