Compositions and methods of production are provided for treating liquid metals, such as desulfurizing, deoxidizing and otherwise purifying and controlling inclusion morphology, by injecting a particulate alloy with a neutral gas carrier below the surface of a molten metal, the alloy being free of silicon and carbon and consisting essentially of calcium, aluminum, iron and/or manganese, with magnesium, barium and alkali metals being present in amounts sufficient to provide desired characteristics associated with their presence.
