Abstract: This paper has mainly described the one-step technical process and equipment for producing tungsten powder having medium particle size. Qualities of tungsten powder reduced by this process and properties of alloys produced using this powder have been described. A comparison of powder qualities and alloy properties between two-step and one-step process has been made. The paper has also given out a series of data showing the comparison of economic results including the yield and productivity of tungsten powder between these two processes. The advantage and feasibility of one-step process can be affirmed by above comparison and analysis Reset
