PURPOSE: To produce a molybdenum multiple powder capable of easily obtaining a high-density sintered body by agitating a molybdenum powder in the soln. of copper salts, drying the powder and reducing the dried material to form the specified amt. of copper layer on the surface of a molybdenum matrix.
CONSTITUTION: Molybdenum powder or molybdenum oxide power is agitated in the aq. of copper salts (CuCl2), the powder is dried, and the dried material is reduced to form 20-50wt.% of copper layer on the surface of a molybdenum metrix, and a Cu-Mo composite powder is obtained. The multiple powder is press-formed at a specified pressure, and the formed product is sintered at 1100-1300°C to obtain the sintered body having ≥90% relative density. The sintered body is rolled to obtain a densified molybdenum composite sheet excellent in strength, heat conductivity, thermal expansion coefficient, etc.
