Crystal types and terms
WebFor gemologists, the scientific definition of a crystal goes right to the atomic level. A crystal is a solid whose atoms are arranged in a "highly ordered" repeating pattern. These patterns are called crystal systems. If a mineral has its atoms arranged in one of them, then that mineral is a crystal. "Crystal 1," photo by Brenda Clarke. WebAug 28, 2024 · All the atoms in a zinc blende structure are 4-coordinate. The zinc blende unit cell is shown in Figure 7.1.9. A number of inter-atomic distances may be calculated for any material with a zinc blende unit cell using the lattice parameter (a). Zn − S = a√3 4 ≈ 0.422a. Zn − Zn = S − S = a √2 ≈ 0.707 a.
