WebIf you read a very old textbook, you may even see something called a “cubic close-packed” (CCP), which is another name for FCC. Because FCC atoms are arranged more closely together than BCC atoms, FCC … 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. Both are based upon sheets of spheres arranged at the vertices of a triangular tiling; they differ in how the sheets are stacked upon one another.

I wouldn’t recommend getting anything above 17 x 13 x 4 inches or anything below 11 x 7 … The three Bravais lattices in the cubic crystal system are: The primitive cubic lattice (cP) consists of one lattice point on each corner of the cube; this means each simple cubic unit cell has in total one lattice point. Each atom at a lattice point is then shared equally between eight adjacent cubes, and the unit cell therefore contains in total one atom (1⁄8 × 8).
