Effect of Particle Microstructure on Powder Resistivity

The resistivity of powder beds is largely set by particle physical attributes, important across applications. Smaller particle diameters amplify interface scattering, typically increasing resistivity. Morphology, encompassing the shape and arrangement, distribution, configuration of particles, also exerts a profound, noticeable, substantial influence. Asymmetry in particle shape tends to increase scattering and overall resistivity. Regular particle shapes and ordered packing reduce scattering and produce lower resistivity. Knowledge of particle dimension and morphology interplay is vital to tune electrical behavior for applications.
