Detection method of particle size distribution of MIM powder


Particle size distribution of injected MIM powder

The particle size distribution of MIM powder is generally tested by laser particle size analyzer, because laser has good monochromaticness and strong directivity. When the beam encounters particle obstruction, part of the light will scatter. The propagation direction of scattered light will form an angle with the propagation direction of the main beam. The size of scattering angle is related to the size of particles. The larger the particles, the smaller the angle of scattered light and the smaller the particles, the larger the angle of the scattered light, the intensity of the scattered light represents the number of the particle size, so that the particle size distribution of the sample can be obtained by measuring the intensity of the scattered light at different angles.
