    Tetragonal crystal lattices 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)
  • Tetragonal system | Definition Facts | Britannica
    Tetragonal system, a group of crystalline solids whose crystals have three mutually perpendicular axes, two of which are equal in length
  • TETRAGONAL | English meaning - Cambridge Dictionary
    Some of the larger crystals are elongate, which gives them a tetragonal rather than cubic appearance When heated from room temperature, the crystals change to show tetragonal symmetry Two crystal forms were obtained; one had tetragonal symmetry, and the second had hexagonal symmetry
