crystal tetragonal rutile

Rutile

Viewed in plane polarized light, the rutile in this thin section mostly lack an acicular or prismatic shape, preferring a more angular, granular morphology.

Rutile is a red, brown or black mineral. It often occurs as golden strands or "Venus Hair Stone" in quartz. When its crystals intersect at 60 degrees whilst growing within other stones it can cause a star effect by reflecting light. Chemical composition: Titanium Oxide Crystal Structure: Tetragonal Hardbess: 6

Rutile

Rutile is found as an accessory mineral in some altered igneous rocks, and in certain gneisses and schists. In groups of acicular crystals it is frequently seen penetrating quartz as in the "fléches d'amour" from Grisons, Switzerland. Crystal Structure. Rutile has a tetragonal unit cell, with unit cell parameters a=4.584Å, and c=2.953Å.

mp-2657: TiO2 (tetragonal, P4_2/mnm, 136)

TiO2 is Rutile structured and crystallizes in the tetragonal P4_2/mnm space group. The structure is three-dimensional. Ti4+ is bonded to six equivalent O2- atoms to form a mixture of corner and edge-sharing TiO6 octahedra. The corner-sharing octahedral tilt angles are 49°. There is four shorter (1.96 Å) and two longer (2.00 Å) Ti–O bond length.

Review of the anatase to rutile phase transformation ...

Abstract. Titanium dioxide, TiO 2, is an important photocatalytic material that exists as two main polymorphs, anatase and rutile.The presence of either or both of these phases impacts on the photocatalytic performance of the material.

Rutile: Mineral information, data and localities.

The name rutile was first introduced by the German geologist Abraham Gottlob Werner in 1800 (cfr. Lampadius 1800 and Ludwig 1803). The name is from the Latin rutilus, meaning "reddish."The mineral was already known under other names, such as "red schorl" and some other names, some of them later recognized as synonyms or varieties.

Anatase - Wikipedia

Anatase is always found as small, isolated and sharply developed crystals, and like the thermodynamically stable rutile (the more commonly occurring polymorph of titanium dioxide), it crystallizes in the tetragonal system. Anatase is metastable at all temperatures and pressures, with rutile being the equilibrium polymorph.
