Role of Particle Size and Form in Powder Resistivity

Electrical resistivity of powders is governed by particle-scale physical properties relevant to many applications. Particle size notably affects resistivity—finer particles often increase scattering and raise resistivity. Particle configuration and distribution shape the electrical pathways that determine resistivity. Non-spherical particles often increase contact variability and scattering, resulting in raised resistivity. Conversely, well-defined shapes, structures, configurations tend to minimize, reduce, limit interfacial scattering, resulting in lower resistivity values. Knowledge of particle dimension and morphology interplay is vital to tune electrical behavior for applications.
