Tetragonal crystal system

 ( Crystal Systems ) 

In crystallography, the tetragonal crystal system is one of the seven . Tetragonal result from stretching a cubic lattice along one of its lattice vectors, so that the cube becomes a rectangular prism with a square base ( a by a) and height ( c, which is different from a).

Bravais lattices There are two tetragonal Bravais lattices: the primitive tetragonal and the body-centered tetragonal.

The body-centered tetragonal lattice is equivalent to the primitive tetragonal lattice with a smaller unit cell, while the face-centered tetragonal lattice is equivalent to the body-centered tetragonal lattice with a smaller unit cell. Cubic-to-Tetragonal Transition
