Particle Geometry Influence on Powder Electrical Behavior

Powder resistivity is a key property influenced by particle physicality for many industrial uses. 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. Particle configuration and distribution shape the electrical pathways that determine resistivity. Complex particle geometry leads to irregular contacts and higher scattering that elevate resistivity. Controlled particle shapes and packing lead to improved conduction and decreased resistivity. Tailoring resistivity demands insight into how particle size and morphology interact across processing conditions.
