Abstract:
1. A method for manufacturing a desulfurizing agent, the method comprising: melting magnesium-aluminum alloy in a crucible at a temperature ranging from about 400° C. to about 800° C. to form a magnesium-aluminum alloy melt; adding an additive selected from the group consisting of alkaline metal compound and alkaline earth metal compound to the magnesium-aluminum alloy melt; stirring the magnesium-aluminum alloy melt for about 1 minute to about 400 minutes; casting the magnesium-aluminum alloy melt in a mold at a room temperature to about 400° C. to form a magnesium-aluminum casting; and cooling the magnesium-aluminum alloy casting, wherein the magnesiam-aluminum alloy melt comprises from about 40 wt % to about 65 wt % aluminum.
