DEVELOPMENT OF THE BRAVAIS LATTICES The 14 Bravais lattices are arrived at by combining one of the seven Crystal System s (or axial systems) with one of the lattice centerings. The lattice centerings are:
Not all combinations of the crystal systems and lattice centerings are needed to describe the possible lattices. There are in total 7 × 6 = 42 combinations, but it can be shown that several of these are in fact equivalent to each other. For example, the monoclinic I lattice can be described by a monoclinic C lattice by different choice of crystal axes. Similarly, all A- or B-centered lattices can be described either by a C- or P-centering. This reduces the number of combinations to 14 conventional Bravais lattices, shown in the table below. The volume of the unit cell can be calculated by evaluating where , and are the lattice vectors. The volumes of the Bravais lattices are given below: SEE ALSO EXTERNAL LINKS
