NettetW is the prototype for BCC. The Body-Centered Cubic (BCC) unit cell can be imagined as a cube with an atom on each corner, and an atom in the cube’s center. It is one of the most common structures for metals. BCC has 2 atoms per unit cell, lattice constant a = 4R/√3, Coordination number CN = 8, and Atomic Packing Factor APF = 68%. 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 rigid … Se mer Common sphere packings taken on by atomic systems are listed below with their corresponding packing fraction. • Hexagonal close-packed (HCP): 0.74 • Face-centered cubic (FCC): 0.74 (also called cubic close … Se mer • Crystal • Packing density • Random close packing Se mer • Schaffer; Saxena; Antolovich; Sanders; Warner (1999).
