| Abstract: | The spherical molybdneum powder is prepared by centrifugal atomization drying. The effect of molybdenum powder pre-processing on the quality of granulation molybdenum powder is analyzed according to the processing route. The relationship between the rotation speed of centrifugal disc,slurry surface tension,slurry density and the diameter of atomization droplet are discussed. And the granulation molybdenum powder size range is determined by the relationship. Then the effect of debond processing on getting ride of impurities,especially the element of C is provided. Finally,the necessity of high temperature strengthening the granulation molybdenum powder is shown. |
