Correspondingly planes of this form ((212), (122), and negative index planes) are denoted by planes of a form: {hkl}, since for cubic crystals implicit in Fig. 1, planes are perpendicular to directions and have equiva-lent indices. It is common practice to denote both planes and directions by (hkl): [hkl] and {hkl}: .

WebThe orientations of planes for a crystal structure can be represented as follows: 1. Determine the intercepts of the plane along the crystal axes (Say 2a, 3b and 1c) 2. Divide intercepts with lattice points translation distances along the axes to obtain intercept of the planes in terms of multiples of unit cell translation lengths. WebHCP is one of the most stable crystal structures and has the highest packing density.
