Abstract

PURPOSE: To enhance the utilization efficiency of a reducing agent and cheaply obtain metallinc Mg in an enhanced yield by blowing hydrogen or an inert gas into mixed starting material melted in an electric furnace to agitate the material in the manufacture of metallic Mg by the Magnetherm process.
CONSTITUTION: Calcined dolomite as a Mg source, ferrosilicon as a reducing agent and bauxite as a slag making agent are charged into a hermetically sealed vacuum electric furnace and melted by supplying an electric current to reduce Mg oxide to metallic Mg. Mg vapor is then taken out of the furnace and condensed to obtain metallic Mg. In the above-mentioned Magnetherm process by blowing hydrogen or an inert gas such as argon the molten material in the furnace is agitated to facilitate uniform mixing of the material, thereby raising the reaction rate, enhancing the unit and yield, and reducing the coat. Thus, metallic Mg is obtd. cheaply.
