Definition of tetragonal in English: tetragonaladjective tɪˈtraɡ(ə)n(ə)ltɛˈtræɡənl Of or denoting a crystal system or three-dimensional geometrical arrangement having three axes at right angles, two of them equal. Example sentencesExamples - Xenotime crystals exhibit tetragonal prisms, dipyramids, and pinacoids, whereas zircon may exhibit first- and second-order tetragonal prisms, dipyramids, and pinacoids.
- The crystals are typically tetragonal dipyramids with pinacoids.
- Superb, equant tetragonal crystals occur on quartz in the junction pockets.
- Furthermore, we see that the molecular rows along the a axes are in perfect alignment with the underlying layers, as one would expect for the tetragonal lattice of the CO-HbC crystals.
- Rutile is a tetragonal mineral famous for its variety of crystal habits and twinning.
- The crystals are stepped tetragonal pyramids (somewhat resembling anatase) associated with chrysocolla.
- Narsarsukite is another tetragonal mineral that can show a tetragonal prismatic habit, particularly when it develops in open cavities.
- Small, black, tetragonal anatase crystals associated with rutile were found on microcline by Kile.
- Zircon (variety cyrtolite) commonly forms curved tetragonal crystals that radiate from a base of biotite crystals and terminate in adjacent feldspar.
Derivatives adverb In addition, Tetragonocrinus has tetragonally positioned accessory canals along the column. Example sentencesExamples - The secondary thermal aging process requiring tight manufacturing controls for proper microstructural development has limited the supplier base for the tetragonally toughened zirconias.
Origin Late 16th century: via late Latin from Greek tetragōnon (neuter of tetragōnos 'four-angled') + -al.
