Rutile Tio2 Film


Favoring the Reactivity of TiO2 Films with Ideal ...

It is shown that there are deposition conditions in reactive sputtering of TiO2 in which the anatase and rutile crystals can coherently arrange in a convenient way that predominantly exposes the anatase facets, a configuration that is expected to favor the photocatalytic activity of the films.

Rutile - Wikipedia

Rutile is a common accessory mineral in high-temperature and high-pressure metamorphic rocks and in igneous rocks.. Thermodynamically, rutile is the most stable polymorph of TiO 2 at all temperatures, exhibiting lower total free energy than metastable phases of anatase or brookite. Consequently, the transformation of the metastable TiO 2 polymorphs to rutile is irreversible.
