摘　　要：提出了一种可以量化钼粉团聚度的定量分析方法即研磨前后费氏粒度比值法,同时探讨了钼粉粒度分布测试中的D90指标能从一定程度反映钼粉的团聚度。当D90较大时,钼粉团聚度相对较高;当D90较小时,钼粉团聚度相对较低。同时使用四钼酸铵、二钼酸铵衍生钼粉做电镜分析,研究钼粉的团聚形态。In this paper,a quantitative method is proposed to quantify the agglomeration of molybdenum powder,that is,the ratio of Fischer-Tropsch granule before and after grinding,and the agglomeration degree of molybdenum powder in D90 index of molybdenum powder particle size distribution test is discussed.When D90 is large,molybdenum powder agglomeration is relatively high,when D90 is small,molybdenum powder agglomeration is relatively low.Electron microscopy analysis is done by using molybdenum powder derived from ammonium tetramolybdate or ammonium dimolybdate to study molybdenum powder agglomeration morphology.
