This part specifies the method for the determination of the particle size distribution of aluminum powder, mg powder and aluminum-magnesium alloy powder by laser diffraction/scattering method, which is suitable for the determination of spherical, granular and flake aluminum mg powder and Miscellaneous powder materials. The summary of the method includes irradiating monochromatic light after the powder sample is fully dispersed, measuring the light scattering phenomenon through a multi-detector and performing photoelectric conversion treatment to obtain the final Particle size distribution information. The schematic diagram of the laser diffraction/scattering device is given in this paper.
