Abstract

A small amount of citric acid coated magnetite nanoparticles was prepared by an already classical coprecipitation method. The nanoparticles were characterized by X Ray Diffraction and by Atomic Force Microscopy. An aqueous dilution experiment was carried on several times and time variation of the refractive index of the nanofluid and of the scattered light intensity were recorded. The results are discussed in connection with aggregate formation..
