METHOD FOR PRODUCTION OF ALLOYS OF METALS WITH PHOSPHOROUS Russian patent published in 1997 - IPC

Abstract RU 2073735 C1

FIELD: iron metallurgy, non-ferrous metallurgy and powder metallurgy. SUBSTANCE: desired alloys are prepared by separate feeding of phosphorous and metal into crucible, the process is followed by heating to temperature being higher than melting point of desired product, but is lower than melting point of origin metals. Phosphorous is preliminary insulated by heat insulation materials on the base of asbestos, paper, glass fiber, carbon and combinations thereof, metal being fed as mixture of chips and pieces or as pieces. Desired product is removed of said crucible as a melt. EFFECT: improved efficiency. 5 cl, 6 tbl
