Based on the different sample loop motion velocity and loading the ultrasonic, the granularity constitution and particle size distribution of minuteness fraction phosphor powder are determined by laser particle size analyzer. Through comparing the normal distribution curve, the average diameter of minuteness fraction phosphor powder is 4.128μm, mid-value of 3.15μm, standard deviation of 3.930 μm, coefficient of variation of 95.10%, mode index of 4.048 μm; the mass fraction of the different particle size is determined. The results show that: the method is accurate to determine powder size and particle size distribution.
