WebThe Face-Centered Cubic (FCC) crystal structure is one of the most common ways that atoms can be arranged in pure solids. FCC is close-packed, which means it has the maximum APF of 0.74. Because FCC … WebThe cubic closed packing is CCP, FCC is cubic structures entered for the face. When we put the atoms in the octahedral void, the packing is of the form of ABCABC, so it is known as CCP, while the unit cell is FCC. These are two different names for the same lattice. 4.
