| titleOfInvention | Low-temperature activation sintering preparation method of high-density molybdenum material |
| abstract | A low-temperature activated sintering preparation method of a high-density molybdenum material belongs to the technical field of powder metallurgy. Weighing ammonium paramolybdate and nickel nitrate hexahydrate according to Mo-x% Ni (x is 0.1-1, mass fraction), adding deionized water to prepare a mixed solution serving as a precursor solution, and preparing precursor powder by adopting a spray drying method; calcining the precursor powder in a muffle furnace; performing two-step hydrogen reduction through a tube furnace; performing high-energy ball milling on the reduced powder at the rotating speed of 350rpm +6rpm and the ball-to-material ratio of 10:1 for 5 hours to obtain powder with the average particle size of 190 nm; carrying out die pressing on the obtained powder, and sintering for 60min at the highest temperature of 1400-1750 ℃ by adopting a high-temperature tungsten net hydrogen furnace; the preparation method provided by the invention has the advantages of low sintering temperature, short sintering time, high efficiency, energy conservation, high product density, fine and uniform grain size and less impurities. |
