Crystals are commonly recognized, macroscopically, by their shape, consisting of flat faces with sharp angles. These shape characteristics are not necessary for a crystal—a crystal is scientifically defined by its microscopic atomic arrangement, not its macroscopic shape—but the characteristic macroscopic shape is often present and easy to see. WebLet us take an elemental crystal with a face-centered cubic (FCC) structure having a lattice constant of a, as an example to illustrate the surface energy on various facets. Each …

"WebCrystal faces are determined by the physical properties of a crystal, such as its structure and symmetry, while cleavage planes are created by the movement of chemical bonds. Additionally, each crystal face is associated with a Miller index, while cleavage planes are always associated with the same index. " - Crystal faces
