Abstract: A method for desulfurizing a metal alloy comprises heating the metal alloy to a molten state. A gaseous desulfurizing compound is bubbled through the molten alloy to form a solid sulfur-containing waste phase and a molten reduced-sulfur alloy phase. The solid waste phase and the molten reduced-sulfur alloy phase are separated. The gaseous desulfurizing compound includes a constituent element selected from the group: alkali metals, alkaline earth metals, and rare earth metals.
