The main objective of this PhD work is to produce nanostructured bulk from anisotropic nanomaterials alloysbased on 3d transition elements (Co and Ni). For using these nanomaterials on an industrial scale, we haveextrapolated the synthesis method (polyol process) from laboratory scale to pilot scale. First, we showed that byvarying the parameters synthesis in laboratory scale we can control not only the morphology but also the size andthe size distribution of the nanoparticles. Indeed, spheres with diameter of 10 nm and nanowires with meanlength of 260 nm and a diameter of 7 nm were obtained for a stoichiometry Co80Ni20. The key parameters of thissynthesis are the concentration of the sodium hydroxide, the nucleation rate, the agitation and...
