WebAtomic packing factor. In 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 ... WebThe atomic packing factor [A.P.F]: It can be defined as the ratio between the volume of the basic atoms of the unit cell (which represent the volume of all atoms in one unit cell ) to the volume of the unit cell it self. For cubic crystals, A.P. F its depends on the riadus of atoms and characrtiziation of chemical bondings .
