sampledescriptionvocabulary1:Tetragonal
  skos:prefLabel "Tetragonal" ;
  skos:definition "1. Of or relating to the shape of a crystal in which two of three axes of each crystal are of the same length and all three axes form right angles (Cambridge dictionary). 2. 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). (Wikipedia). 3.  one of the structural categories to which crystalline solids can be assigned. Crystals in this system are referred to three mutually perpendicular axes, two of which are equal in length. (Britannica)."^^ns0:None ;
