D Hkl
Miller indices form a notation system in crystallography for planes in crystal bravais lattices.
D hkl. The normal to the plane with indices hkl is the direction hkl. A web based program identified by the clickable icon is provided here to demonstrate the calculation of hkl values and d spacings. D hkl dari kristal dengan sumbu orthogonal α β r 90 orthogonal menunjukkan bahwa 2 vektor saling tegak lurus satu sama lain dalam hal ini 3 vektor yaitu x y z kebalikan atau reciprocal dari titik potong hkl adalah bidang xyz.

It is frequently very useful in the analysis of powder diffraction data to be able to calculate a set of hkl values d spacings and equivalent 2θ values from a bravais lattice of given unit cell dimensions. How to calculate hkl d spacing of perovskite materials from xrd data.

The distance d between adjacent planes of a set of parallel planes of the indices h k i is given by where a is the edge of the cube.
Normally the planes with low index numbers have wide interplanar spacing compared with those having high index numbers.
