Size distribution of a metallic polydispersion through capacitive measurements in a sedimentation experiment Article uri icon

abstract

  • A sedimentation technique to determine size distributions of metallic polydispersions was presented. The effective dielectric constant in a cylindrical cell at a fixed frequency was measured after suspending particles in a viscous fluid-like glycerol and following their sedimentation. The size was obtained using an inversion procedure of data, based on Maxwell-Garnet effective medium theory and Stokes law. Three different stainless steel dispersions were studied using the technique and compared with the traditional sizing method.
