How Particle Dimensions and Morphology Influence Resistivity

Powder resistivity strongly depends on particle physical traits and affects many processing technologies. Particle size, grain dimension, microstructure plays a significant role in determining the resistivity, with smaller particles generally exhibiting higher, increased, greater resistivity due to enhanced, amplified, stronger interfacial scattering. Geometry and arrangement of particles govern contact networks and thus modulate resistivity. Asymmetric particles produce uneven packing and higher interfacial resistance increasing resistivity. Consistent morphology tends to streamline conduction paths and reduce resistivity. Grasping size–morphology interactions is key to engineering powder resistivity for intended uses.
