Closed packing
The FCC and HCP packings are the densest known packings of equal spheres with the highest symmetry (smallest repeat units). Denser sphere packings are known, but they involve unequal sphere packing. A packing density of 1, filling space completely, requires non-spherical shapes, such as honeycombs. Replacing each contact point between two spheres with an edge connecting the centers of the t… Webclosed-packed position. , close-packed position.

WebThe tight packing of the hexagon is denoted as HCP. In one repeated unit, this arrangement has two layers of spheres. The main distinction between hexagonal close packing and cubic close packing is that there are 6 … WebThe packing efficiency is the fraction of volume in a crystal structure that is occupied by constituent particles, rather than empty space. In order to find this, the volume of the spheres needs to be divided by the total volume (including empty spaces) occupied by the packed spheres. For both HCP and CCP, the packing efficiency is 74.05 %.
