摘　　要：对钼粉的费氏粒度、粒度分布、颗粒尺寸、微观形貌和比表面积进行测量,并结合理论计算,研究了钼粉的粒度与比表面积之间的关系。结果表明:钼粉的比表面积与平均粒度成反比例函数关系,颗粒尺寸与实测比表面积规律大致符合理论计算的趋势;当钼粉颗粒形状为球形时,颗粒尺寸越均匀、团聚程度越低,实测的比表面积结果越接近理论计算的结果。The relationship between the particle size and specific surface area of molybdenum powder was studied by measuring the Fei’s particle size,size distribution,particle size,microstructure and specific surface area of molybdenum powder,and combining theoretical calculations.The results show that the specific surface area of molybdenum powder was inversely proportional to the average particle size,and the relationship rule between particle size and measured specific surface area resulted roughly conforms to the trend of theoretical calculations.When the shape of molybdenum powder particles was spherical,the more uniform the particle size and the lower the degree of agglomeration,the closer the measured specific surface area results were to the theoretical calculation results.
