摘　　要：作为工业上生产钼粉的常用还原介质,氢气的质量对中间产物二氧化钼及钼粉的质量有着重要的影响。使用不同纯度的氢气一次还原生产二氧化钼,并将二氧化钼在完全相同的工艺条件下还原成钼粉。通过对二氧化钼的费氏平均粒度、粒度分布、电镜形貌及钼粉的费氏平均粒度、粒度分布、电镜形貌进行对比,总结了氢气纯度对二氧化钼及钼粉质量的影响。As a commonly used reducing medium for industrial production of molybdenum powder,the quality of hydrogen has a significant impact on the intermediate products molybdenum dioxide and the quality of molybdenum powder.Using hydrogen of different purity for primary reduction to produce molybdenum dioxide,and reducing molybdenum dioxide into molybdenum powder under identical process conditions.The influence of hydrogen purity on the quality of molybdenum dioxide and molybdenum powder was summarized by comparing the information related to the average particle size,particle size distribution,electron microscope morphology of molybdenum dioxide and the average particle size,particle size distribution,electron microscope morphology of molybdenum powder.
