Abstract
AbstractProduction methods of Fe3O4grain and MgS grain have been introduced. Fe3O4grain was produced in an Ar gas pressure range of 25 to 100 Torr by evaporating FeO powder. The growth of Fe3O4have been discussed as the result of oxidation of Fe grains. MgS grain produced by the reaction of Mg and S vapors grew in the coagulation of tiny cubic sulfide.
