In geometry, close-packing of equal spheres is a dense arrangement of congruent spheres in an infinite, regular arrangement (or lattice). Carl Friedrich Gauss proved that the highest average density – that is, the greatest fraction of space occupied by spheres – that can be achieved by a lattice packing is Visa mer There are two simple regular lattices that achieve this highest average density. They are called face-centered cubic (FCC) (also called cubic close packed) and hexagonal close-packed (HCP), based on their symmetry. … Visa mer Crystallographic features of HCP systems, such as vectors and atomic plane families, can be described using a four-value Miller index notation ( hkil ) in which the third index i denotes a … Visa mer • Cubic crystal system • Hermite constant • Random close pack Visa mer When forming any sphere-packing lattice, the first fact to notice is that whenever two spheres touch a straight line may be drawn from the … Visa mer The FCC and HCP packings are the densest known packings of equal spheres with the highest symmetry (smallest repeat units).
