The translational invariance of a crystal lattice is described by a set of unit cell, direct lattice basis vectors (contravariant or polar) called a, b, and c, or equivalently by the lattice parameters, i.e. the magnitudes of the vectors, called a, b and c, and the angles between them, called α (between b and c), β (between c and a), and γ (between a and b). Direct lattice vectors have components measured in distance units, like meters (m) or angstroms (Å). WebJun 16, 2024 · These observations show that the dissolution process is steered by distinct crystallographic zones with a clear hierarchical organization. ... This hourglass zone is overgrown by zonal features (Fig. 3, A and D). The above observations are evidence of multistage crystal growth, where the growth mechanism changes from sectorial to zonal …
