  • 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 data

  • A Gentle Sedimentation Process for Size-Selecting Porous

    Air-dried and supercritically-dried pSi powders are shown to have, for example, their median diameter d (0.5) particle sizes reduced from 13 to 1 μm and from 20 to 3 μm, using sedimentation times of 6 and 2 h respectively. Such filtered microparticles also have much narrower size distributions and are hence suitable for administration in 27 gauge microneedles, commonly used in intravitreal
