Description

<p>Preparation of Mg particles were carried out by using a pulsed wire discharge method, which is a physical vapor method in organic matter fume/vapor and is beneficial for passivated metal nanosized powders. From results of powder X-ray diffraction, the sample consisted of single-phase Mg. Electron diffraction and transmission electron microscopy observations revealed that Mg submicron particles were seen even though the presence of fine MgO particles. After an oxidation test at room temperature in air for one month, the oxidation did not progress. From these results, it was concluded that alkaline earth metal particles can be mass-produced by the pulsed wire discharge.</p>
