WebIn total, there are 2 atoms in the BCC unit cell. If we divide the volume of 2 atoms by the volume of the unit cell ( ), we find that the atomic packing factor for a body-centered cubic crystal is: Face-Centered Cubic (FCC) Lattice Length and APF This should be familiar by now. Volume of the atoms divided by volume of the unit cell. WebApr 19, 2016 · Show that the atomic packing factor for BCC is 0.68. Solution The atomic packing factor is defined as the ratio of sphere volume to the total unit cell volume, or APF = VS VC Since there are two spheres associated with each unit cell for BCC ⎛ 4π R 3 ⎞ 8π R 3 VS = 2 (sphere volume) = 2 ⎜ ⎟= 3 ⎝ 3 ⎠
