Close-packed hexagonal structure
WebHexagonal close-packed structure. Credit: Callister & Rethwisch 5e. It turns out that face-centered cubic and hexagonal close-packed crystal structures pack atoms equally tightly. Some metals with hexagonal … WebBecause this structure is composed of alternating planes of hexagonal closest-packed spheres, it is called a hexagonal closest-packed structure. Each sphere touches three spheres in the plane above, three spheres in the plane below, and six spheres in the same plane, as shown in the figure below.

WebThe lattice of the hexagonal close packed crystal is hexagonal and a basis of two atoms is placed in the same orientation on each lattice point. The diagrams below illustrate the geometry and space filling of this … WebThe bcc lattice, although cubic, is not closely packed and forms strong metals. Alpha-iron and tungsten have the bcc form. The fcc lattice is both cubic and closely packed and forms more ductile materials. Gamma-iron, silver, gold, and lead have fcc structures. Finally, HCP lattices are closely packed, but not cubic.
