Comparison of ER70S-2 with ER309L in Synthesis of Magnetic Nanoparticles using Arc-Discharge Method

Abstract

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.
