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). WebCubic Close Packing Closest packed means that the atoms are packed together as closely as possible. The FCC unit cell is actually made of four cubic close packed layers (click to show the unit cell with layers). The first layer of atoms pack together as close as possible. (click to show layer " A ").
