Unveiling The Significance Of Close-Packed Structures: Maximizing Density, Stability, And Material Properties
Close-packed positions describe highly efficient arrangements of spheres achieving maximum density and stability. Face-centered cubic (FCC) and hexagonal close-packed (HCP) are prominent close-packing structures with coordination numbers of 12 and 14, respectively. Their layered arrangements and high packing fractions (0.74 for FCC and 0.74 for HCP) optimize space utilization. Coordination number and packing fraction depend …
