Packing factors
WebHexagonal Close-Packed Atomic Packing Factor. The Atomic Packing Factor (APF) is essentially the density of the unit cell. Since we use the hard sphere model, each point inside the cell is either part of an atom, or part of the void. APF is basically the fraction of atoms to void. For a full article explaining APF, check out this link. APF is the WebMar 21, 2024 · What is Packing factor, Fp ? Packing factor is the ration of packing surface area per unit volume to cube of the packing's void fraction. Holds the unit of m-1. You may also like: [How to] Calculate rate of …
