Axe de zone (Fr). Zonenachse (Ge). Eje de zona (Sp). (Ru).

A zone axis is a lattice row parallel to the intersection of two (or more) families of lattices planes. It is denoted by [u v w]. A zone axis [u v w] is parallel to a family of lattice planes of Miller indices (hkl) if:

uh + vk + wl = 0

The indices of the zone axis defined by two lattice planes ([math] h_1, k_1, l_1 [/math]), ([math] h_2, k_2, l_2[/math]) are given by:


Three lattice planes have a common zone axis (are in zone) if their Miller indices satisfy the relation:
