Abstract
Provided is a method by which a low-oxygen and high-density molybdenum target can be efficiently obtained, while fully utilizing the characteristics of each molybdenum (Mo) starting material powder. The present invention provides a method for producing a molybdenum target, wherein a mixed powder that is obtained by mixing a molybdenum powder A, which is prepared by reducing molybdenum oxide and then crushing the resulting so as to have an average particle diameter of 2-15 μm, and a molybdenum powder B, which is prepared by crushing a molybdenum bulk starting material having a density of not less than 6.64×10 (kg/m) so as to have an average particle diameter of 50-2,000 μm, is sintered under pressure.
