Deposits. Rutile is formed at deposits of different types, mainly in the process of metamorphism. It is well preserved at placers. ... A new type of deposits of anatase is metasomatic of the Murun alkali massif in Yakutia, where the size of crystals of anatase reaches 2 cm. In the Khabarovsk Region, at the Udacha deposit, 60 km. to the south from the massif Kondior, they discovered .

The anatase and rutile isolates contained 74–93% (Ti,Fe)O 2 with 0·5–3·1% Fe. The other constituents of the isolates were muscovite of mica (0·3–7%), quartz (0–9%) and amorphous relics of vermiculite and/or kaolinite (6–19%). Rutile, muscovite and quartz appear to be detrital but the anatase and relics are probably authigenic.

· Xray absorption spectroscopy suggests that the relatively low sample temperature (175 °C) results in an anatase film despite the rutile template of the substrate. Using ambient pressure xray photoelectron spectroscopy, the adsorption of TTIP was found to be selflimiting, even at room temperature. No molecular water was found to adsorb on the surface.

After this reaction, PbO 2 deposits were seen on the {011} face of the rutile particles. On the anatase particles, PbO 2 deposits were observed in a larger amount on the {001} face than on the {011} face. These results indie that the crystal faces help in the separation of electrons and holes, and that this effect is stronger for the rutile ...

fifth of anatase [6]. In contrast to rutile containing Vanadium and Iron, pure rutile shows no photoactivity [5]. However, depending on the type of elements presents in the rutile as impurity, it could show some photo activity. For example, naturally occurring rutile usually contains trace elements such as Vanadium and Iron and these elements enhance photoalysis [78]. Since the mineral ore ...
