Zusammenfassung:PREPARATION OF RARE EARTH AND JAMES R. GOLDSMITH OTHER METAL ALLOYS CONTAINING AlEC MITCHELL ALUMINUM AND SILICON J. MALCOLM GRAY A method for making an alloy of aluminum and silicon with rare earth metals and metals of Groups 4b, 5b and 6b of the Periodic Table in which the flux system CaF2-CaO-A12O3 is used as a solvent to provide a reactive medium for the reactions through which alloys are formed, the method comprising reducing the oxides of the alloying metals with aluminum in the presence of silicon in the flux maintained liquid at a temperature between about 1250.degree.C 1600.degree.C while maintaining the flux basic to suppress the activity of A12O3 and forming the alloys in the flux from the reduced metals.
