METHOD FOR MAKING TANTALUM INGOTS Russian patent published in 2003 - IPC

Abstract RU 2204618 C1

FIELD: metallurgy of refractory metals and alloys, namely processes for making tantalum ingots at using waste materials of tantalum charge by means of electron-beam refining. SUBSTANCE: method comprises steps of electron-beam refining of consumable billet made of tantalum plate in the form of lumps and(or) waste of rolled stock production placed to melt metallic container; selecting material of container according to its melting temperature with use of relation 0,5≤T_к/T_Ta≤0,7, where T_к - melting temperature of metallic container; T_Ta - melting temperature of tantalum. EFFECT: possibility for producing high-quality tantalum ingots of lump charge and(or) waste materials, enhanced technical and economical factors. 2 tbl
