Effect of Particle Microstructure on Powder Resistivity

Powder resistivity hinges on particle morphology and size, impacting multiple technology domains. Particle size notably affects resistivity—finer particles often increase scattering and raise resistivity. Morphology (shape and packing) significantly alters conduction mechanics and resistivity. Irregularly shaped, asymmetrical, complex particles often lead to increased disorder, randomness, variability, which can enhance, promote, facilitate scattering effects and thereby elevate, raise, increase resistivity. Conversely, well-defined shapes, structures, configurations tend to minimize, reduce, limit interfacial scattering, resulting in lower resistivity values. Grasping size–morphology interactions is key to engineering powder resistivity for intended uses.
