Derive packing efficiency of fcc unit cell
WebSep 10, 2024 · Packing Efficiency Formula The formula for effective packing is, Packing efficiency = (Volume occupied by particles in unit cell / Total volume of unit cell) × 100 … WebIn crystallography, atomic packing factor (APF), packing efficiency, or packing fraction is the fraction of volume in a crystal structure that is occupied by constituent particles. It is a dimensionless quantity and always less than unity. In atomic systems, by convention, the APF is determined by assuming that atoms are rigid spheres.

WebThe structures of crystalline metals and simple ionic compounds can be described in terms of packing of spheres. Metal atoms can pack in primitive cubic, body-centered cubic, and face-centered cubic structures. Each packing has its own characteristics with respect to the volume occupied by the atoms and the closeness of the packing.
