Mg has been known as a light-weight and hydrogyen-absorbing material. However, because of the high oxidation speed, it was difficult to prepare Mg particles. In this work, pulsed wire discharge(PWD), whch had been effective for preparation of other metal nanosized powders, was utilized to prepare Mg particles. From the XRD and TEM/SAD analysis data, it was found that Mg particles with an average size of 76nm was prepared even though MgO nanoparticles were coexisting. After an oxidation test at room temperature in air for one month, no significant oxidation was detected. From these results, it was found that Mg particles can be prepared by PWD.
