Crystallographic planes
WebCrystallographic Planes • Miller Indices: Reciprocals of the (three) axial intercepts for a plane, cleared of fractions & common multiples. All parallel planes have same Miller indices. • Algorithm 1. Read off intercepts of plane with axes in terms of a, b, c 2. Take reciprocals of intercepts 3.Reduce to smallest integer values WebThe planes are denoted with the symbol ( hkl ), where h, k, and l are integers. A given point in space, [ xyz ], is on a plane defined by indices ( hkl ) that passes through the origin, if xh + yk + zl = 0. Planes are known as lattice planes if a lattice point is on the plane.

Crystallography is the experimental science of determining the arrangement of atoms in crystalline solids. Crystallography is a fundamental subject in the fields of materials science and solid-state physics (condensed matter physics). The word "crystallography" is derived from the Greek word κρύσταλλος (krystallos) "clear ice, rock-crystal", with its meaning extending to all solids with some deg…
