Atomic Packing factor for SC BCC FCC and HCP In crystallography, atomic packing factor (APF), packing efficiency or packing fraction is the fraction of volume in a crystal structure that is occupied by constituent particles. It is dimensionless and always less than...

Diamond and Graphite Graphite and diamond are two of the most interesting minerals. They are identical chemically—both are composed of carbon (C), but physically, they are very different. Minerals which have the same chemistry but different crystal structures are...

Miller Indices Miller introduced a set of three number of designate a plane in a crystal.This set of three numbers are known as Miller indices of the concerned plane. Definition: Miller indices is defined as the reciprocal of the intercepts made by the plane on the...

Lattice Plane In crystallography, a lattice plane of a given Bravais lattice is a plane (or family of parallel planes) whose intersections with the lattice (or any crystalline structure of that lattice) are periodic (i.e. are described by 2d Bravais lattices) and...

Bravais lattice Crystals are grouped into seven crystal systems, according to characteristic symmetry. The characteristic symmetry is the minimum symmetry of that system. The characteristic symmetry of a crystal is a combination of one or more rotations and...

Unit cell Unit cell can be considered as the building block of a crystal. It has the same symmetry as the entire crystal. When we arrange the unit cell in 3D, we get the bulk crystal. In other words, it can be described...
