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.

WebSep 12, 2024 · The energy per ion pair needed to separate the crystal into ions is therefore Udiss = αke2 r0 (1 − 1 n). This is the dissociation energy of the solid. The dissociation … WebSep 7, 2024 · Crystal packing. We can now define some relevant metrics to describe the atomic density in different lattices and even along different directions within the crystal. … A most important crystal property that can be calculated by this model is the packing energy. For an ionic crystal, if the coordinates and charges of all ions in the crystal model are known, the interionic distances and hence the Coulombic energy can be calculated.
