Crystal notation
WebAs a crystal is periodic, there exist families of equivalent directions and planes. Notation allows for distinction between a specific direction or plane and families of such. Use the [ ] notation to identify a specific direction (ie [1,0,-1]). Use the < > notation to identify a family of equivalent directions (ie <110>).

WebFeb 17, 2024 · The notation (hkl) is used to indicate Miller indices in a general sense, where h, k, and l are the Miller indices of a cubic crystal plane for the x, y, and z axes, respectively. The following figure shows three of the most important crystallographic planes of cubic crystal structures. WebTo designate a crystal form (which could imply many faces) we use the Miller Index, or Miller-Bravais Index notation enclosing the indices in curly braces, i.e. {hkl} or {hkil} Such notation is called a form symbol. As an example, look at the crystal drawing shown here. This crystal is the same orthorhombic crystal discussed above.
