WebCrystals are allocated to seven systems according to the number of these axes, their lengths and the angles between them. There is a conventional notation for the lettering and order of the crystallographic axes. That running from front to back is the “a”‘ axis. If the horizontal axes are equal in length, they are referred to as a 1 and a ... WebThe Cubic crystal system is also known as the "isometric" system. The Cubic (Isometric) crystal system is characterized by its total symmetry. The Cubic system has three crystallographic axes that are all perpendicular to each other and equal in length. The cubic system has one lattice point on each of the cube's four corners. 2. Hexagonal
