Crystal-packing
WebApr 10, 2004 · The question of why molecules pack to form particular crystal structures is occupying many researchers throughout the scientific community. Much emphasis has … 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.
