Iron-oxide based Magnetic nanoparticles were synthesized using Arc-discharge method in which ER70S-2 and
ER309L weld wires were used as electrodes. In this experiment KCl salt is used as electrolyte due of its easy
availability. While comparing KCl with any other salt, it is found that its reaction rate is high due to which good
quantity of nanoparticles can be produced in very less time. Since the most widely used natural element on earth is
iron, therefore it finds many applications in biomedical and in many other research areas when these particles are in
nano form. Many experiments were carried out using ER70S-2 and ER309L weld wires as electrodes. The obtained
size and chemical composition of the nanoparticles will be discussed briefly using XRD and EDAX characterization
techniques.
