Though closely resembling the tetragonal torbernite in form, it crystallizes in the orthorhombic system and is optically biaxial. From Wordnik.com. [Encyclopaedia Britannica, 11th Edition, Volume 3, Part 1, Slice 1 "Austria, Lower" to "Bacon"] Reference
Rutile is made up mostly of titanium dioxide with two rarer polymorphs anatase or octahedrite, which is a tetragonal mineral of pseudo-octahedral habit, and brookite, which is an orthorhombic mineral, the Doctor explained to her. From Wordnik.com. [Update] Reference
One of the most arresting pictures is Karl Benjamin's 1957 oil-on-linen "Small Planes: White, Blue, and Pink," whose multiple tetragonal shapes look like boxes that have been mounted, or spread, but simultaneously seem to float weightlessly on the picture plane.

Having determined the identity in chemical composition of the crystals, it was thought that there might be a difference of form of the crystals in the various plants, from the fact that calcium oxalate crystallizes both in the tetragonal and the monoclinic systems.

A superconducting region appears as likely in the orthorhombic/antiferromagnetic (AFM) state as in the tetragonal/paramagnetic state. From Wordnik.com. [Naturejobs - All Jobs] Reference
"The bismuth ferrite wants to be in a rhombohedral phase but the epitaxial strain forces it into a tetragonal phase, creating a morphotropic phase boundary.". From Wordnik.com. [PhysOrg.com - latest science and technology news stories] Reference
A modest dc electric field markedly reduced the tensile flow stress at high temperatures in three polycrystalline oxides, i.e. MgO, Al2O3 and yttria-stabilized tetragonal ZrO2 (Y-TZP). From Wordnik.com. [Next Big Future] Reference
This high-resolution electron micrograph shows the boundaries between rhombohedral (R phase) and tetragonal (T phase) regions -- indicated by dashed lines -- in a thin film of bismuth ferrite under epitaxial strain.

"The resolution of TEAM 0.5, which is currently the highest in the world for an electron microscope, made it possible for us to image the atomic structure of both the tetragonal and rhombohedral phases and their interfaces," says Ramesh.

We show that the pathway associated with successive cytokinesis (cytoplasm is partitioned after each meiotic division) is restricted to wall formation mediated by centrifugally developing cell plates, and tetragonal (or decussate, T-shaped, linear) tetrads. From Wordnik.com. [Seeds Aside] Reference
Tin possesses a crystallized structure, and can be obtained in well-formed crystals of the tetragonal or quadratic system (form right square prism), and on account of this crystalline structure, a bar of tin when bent emits a creaking sound, termed the "cry of tin;" the purer the tin the more marked the cry.

Beginning with the highest, we have -- (1) the cubic system, with nine planes of symmetry; (2) the hexagonal, with seven planes; (3) the tetragonal, with five planes; (4) the rhombic, with three planes; (5) the monoclinic, with one plane; (6) the triclinic, with no plane of symmetry at all.

The third of the six systems enumerated above, the tetragonal -- or the quadratic, square prismatic, dimetric, or pyramidal -- system has three axes like the cubic, but, in this case, though they are all at right angles, two only of them are equal, the third, consequently, unequal. From Wordnik.com. [The Chemistry, Properties and Tests of Precious Stones] Reference
The fourth system, the rhombic -- or orthorhombic, or prismatic, or trimetric -- has, like the tetragonal, three axes; but in this case, none of them are equal, though the two lateral axes are at right angles to each other, and to the vertical axis, which may vary in length, more so even than the other two.
