METHOD OF RECEIVING OF ACTIVE NICKEL POWDER

摘要

FIELD: metallurgy. ^ SUBSTANCE: invention relates to non-ferrous metallurgy and can be used for receiving of nickel powder from nickel protoxide. Nickel protoxide is reduced in pipe furnace at temperature 1000-1150C by solid carbon- and hydrogenous reducer, fed into furnace in amount 15-21% of mass of reduced nickel protoxide. Reduced powder is cooled by water up to the temperature 22040C and it is extracted active fraction of powder fineness -1+0.2 mm. From powder it is separated residual carbon and ashes of solid reducer. It is used solid reducer with content of volatile components 10-30%. ^ EFFECT: received nickel powder is defined by metallisation degree more than 90% and cement-grout activity more than 80%. ^ 4 cl, 1 tbl
