摘　　要：利用激光衍射法对钼、钨粉末进行粒度测量,分别从超声方式和超声时间上对测量条件进行研究。结果表明:对钼粉,宜在大功率超声装置上将样品分散10 min后进行测量;对于钨粉,宜在大功率超声装置上将样品分散20 min后进行测量。Particle size of Mo and W powders was measured by laser diffraction method. This investigation focused on the influence of ultrasonic power and dispersion time on particle size. The results show that strong power ultrasonic is suitable for Mo and W powder. Because of different particle shapes and agglomeration status, the dispersion time of 10 minutes is enough for Mo powder and 20 minutes for W powder.
