Crystallography formula

  • What does 111 mean in crystallography?

    In the monoclinic, triclinic, and orthorhombic crystal systems, the form {111} is a general form because in these systems faces of this form will intersect the a, b, and c axes at different lengths because the unit lengths are different on each axis..

  • What is the formula for crystallographic direction?

    For instance the crystallographic direction described in Miller indices as [uvw] is given by the translation vector t=ua1+va2+wc in terms of the three basis vectors of the hexagonal lattice {a1,a2,c}..

  • Mathematical crystallography is the branch of crystallography dealing specifically with the fundamental properties of symmetry and periodicity of crystals, topological properties of crystal structures, twins, modular and modulated structures, polytypes and OD structures, as well as the symmetry aspects of phase
  • To solve a crystal structure from XRD, the diffraction pattern obtained from a sample is compared to reference patterns of structures from the target chemical space.
    Subsequently, the matching structure(s) can be further refined with techniques such as Rietveld refinement [1].

The equation, xh + yk + zl = 1, implies that the first plane from the origin, with indices (hkl), intercepts the crystallographic axes at a/h, b/k and c/l. So,
