WebWhat are packing factors of BCC, FCC and HCP crystal structure? APF, the atomic packing factor, which is the fraction of the volume of the cell actually occupied by the hard spheres. APF = Sum of atomic volumes/Volume of cell. APF of BCC structure is 0.68 APF of FCC structure is 0.74 APF of HCP structure is 0.74.
