Sedimentation analysis of metal powders SpringerLink

1/5/1965· The authors investigated the possibility of applying sedimentation analysis to the determination of the particle size distribution of metal powders obtained by various methods, as well as the analytical method proposed byTsyurupa for calculating and plotting the distribution curve. The results of the sedimentation analysis of an aluminum-magnesium powder (PAM-3) were compared with dataPowder Particle an overview ScienceDirect Topics,ASTM B761-06 Standard test method for particle size distribution of metal powders and related compounds by X-ray monitoring of gravity sedimentation. This test method is applicable to particles of uniform density and composition, having particle size distribution between 0.1 and 100 m.

Sedimentation determines size by measuring the sinking of particles in a liquid. Particle Structure . The structure, or shape, of particles is a major factor in a powder processing operation. Material and method of powder production are the main variables determining powder shape. Particles of a certain powder may have similar shapes but no particle shapes are exactly the same.
