Main characteristics of titanium dioxide

The chemical composition of rutile mainly includes TiO2, Ti60%, sometimes containing Fe, Nb, Ta, Cr, Sn, etc; Its name comes from the word "Rulle"; From the Latin word Rutilus, it refers to red, symbolizing the color of rutile.

Its main characteristics are: its square columnar shape, twin crystals, and color are identified as identification features; Can be distinguished from cassiterite; Insoluble in acids, adding sodium carbonate for melting can dissolve in silicic acid. If hydrogen peroxide is added, the solution can turn yellow.

Because it is formed under high temperature conditions and mainly occurs in gold bearing quartz veins and pegmatite veins of metamorphic rock series. In addition, it appears as a secondary mineral in igneous rocks and is often found in granular form in gneiss; Due to its high chemical stability, rutile is often transformed into sand mines after rock weathering.

Rutile, as a bymineral, is found in rocks such as granite, pegmatite, gneiss, mica schist, and eclogite, and is also distributed in sedimentary rocks or sediments in the form of debris or sand ore. Rutile is mainly used for extracting titanium and manufacturing white pigments
