摘　　要：本文通过增加原料活性,降低还原温度,制备出粒度小于1.0 um的钼粉。由于超细钼粉低温活化烧结特性,在烧结过程中降低烧结温度,减少烧结时间,有效地提高钼板坯的晶粒数,同时降低了车间的生产成本。The molybdenum powders with grain size of less than 1.0 um are produced by increasing the activity of raw materials and decreasing reduction temperature in this paper. The lower sintering temperatures and shorter sintering time are used in the sintering process for fine molybdenum powder sintering characteristics of low-temperature activation. It is achieved to effectively reduce plant production costs and enhance the crystalline grain quantity of molybdenum slab.
