Abstract

PURPOSE: To manufacture a uniform mixture of metallic W powder and metallic Re powder by a method in which ammonium tungstate is mixed with metallic Re or an Re compound aqueous solution, and the mixture is concentrated to dryness and reduced by hydrogen.
CONSTITUTION: An ammonium salt of tungsten, e.g., ammonium tungstate, ammonium paratungstate, etc., is mixed with metallic Re or an aqueous solution of an Re compound, e.g., rhenic acid, perrhenic acid, ammonium perrhenate, etc. The mixture thus obtained is heated for evaporation to dryness according to need, and the dried mixture is heated at 300W500°C in an atmosphere of hydrogen for primary reduction and then at 600W1,000°C in the same atmosphere for secondary reduction to obtain a uniform mixture of metallic W powder and metallic Re powder.
