Size and Shape Dependencies of Powder Resistivity

Powder resistivity is a crucial factor in various applications, processes, technologies, heavily influenced by the physical characteristics of powder particles. 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. Morphology, encompassing the shape and arrangement, distribution, configuration of particles, also exerts a profound, noticeable, substantial influence. 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. Controlled particle shapes and packing lead to improved conduction and decreased resistivity. Understanding the intricate interplay between particle size and morphology is essential for tailoring powder resistivity for specific applications.
