  • Reduction-melting process to form rare earth-transition metal alloys and the alloys
    Patent number: 6309441
    Abstract: Rare earth alloy compositions, such as the neodymium iron boron (NdFeB) alloy are made by a Reduction-Melting process. The Reduction-Melting process comprises preparing a primary electrode containing at least one compound or metal to be reduced to form a refined metal or metal alloy ingot; placing the electrode in an electroslag refining furnace; passing a current through the electrode into a molten flux or slag to melt the electrode; reducing the metal or compound in the slag while forming an oxide by-product; collecting melted metal or metal alloy droplets falling through the slag; forming an ingot of the metal or metal alloy from the melted droplets; and collecting the solid oxide byproducts in the slag.
