The Impact of Particle Size and Morphology on Powder Resistivity

Powder electrical response is dictated by particle-level properties and matters in varied processes. Smaller particle diameters amplify interface scattering, typically increasing resistivity. Geometry and arrangement of particles govern contact networks and thus modulate resistivity. Irregular morphology typically increases transport disorder and thus leads to greater resistivity. Ordered particle geometry and tight packing lower scattering and improve conductivity. Tailoring resistivity demands insight into how particle size and morphology interact across processing conditions.
