Difference Between Rutile and Anatase Titanium Dioxide

Titanium dioxide Tio2 has two forms: rutile and anatase. Rutile is deep red while anatase is yellow to blue. Rutile has a high absorbance property than anatase. Rutile and anatase are both used in the white pigmentation of paints, paper, and ceramics.

What is Anatase TiO2?

Anatase is a metastable mineral form of titanium dioxide (TiO₂). The mineral in natural forms is mostly encountered as a black solid, although the pure material is colorless or white. Two other naturally occurring mineral forms of TiO₂ are known, brookite and rutile.

Why is rutile more stable than anatase?

Generally, anatase is more active than rutile, but no consensus exists to explain this difference. ... This shows that charge carriers excited deeper in the bulk contribute to surface reactions in anatase than in rutile. Furthermore, we measure surface orientation dependent activity on rutile single crystals.

What is titanium dioxide rutile?

Titanium dioxide is a titanium oxide with the formula TiO2. A naturally occurring oxide sourced from ilmenite, rutile and anatase, it has a wide range of applications. It has a role as a food colouring.

What is the common name for titanium dioxide?

CHEBI:32234 - titanium dioxide

Titanium dioxide, also known as titanium(IV) oxide or titania , is the naturally occurring oxide of titanium, chemical formula TiO2.

Why is TiO2 a photocatalyst?

Titanium dioxide (TiO2) has been widely used as a photocatalyst in many environmental and energy applications due to its efficient photoactivity, high stability, low cost, and safety to the environment and humans. However, its large band gap energy, ca.

Is titanium dioxide a metal?

Titanium, the ninth most common element in the Earth's crust, is a metal commonly found in plants and animals. Titanium naturally interacts with oxygen to form titanium oxides, commonly found in ores, indigenous dusts, sands and soils.

What does rutile mean?

: a reddish-brown to black mineral that consists of titanium dioxide usually with a little iron and has a brilliant metallic or adamantine luster.

What is the use of rutile?

The main uses for rutile are the manufacture of refractory ceramic, as a pigment, and for the production of titanium metal. Finely powdered rutile is a brilliant white pigment and is used in paints, plastics, paper, foods, and other applications that call for a bright white color.

Where is Brookite found?

It typically occurs as brown, metallic crystals in veins in gneiss and schist; it is also found in placer deposits and, less commonly, in zones of contact metamorphism. It is widespread in veins in the Alps; in Fronolen, north Wales, it forms crystals on crevice walls in diabase.

Is titanium dioxide cancerous?

The World Health Organisation's International Agency for Research on Cancer (IARC) has determined that titanium dioxide is a “possible carcinogen for humans”. In 2017 the French Government's scientific assessment found that titanium dioxide is a carcinogen when it is inhaled.

Does titanium dioxide kill viruses?

Titanium dioxide treated materials have been shown to be effective against a wide range of microorganisms including protozoa algae, fungi, bacteria, and viruses.

What are the dangers of titanium dioxide?

What are the potential health effects of titanium dioxide?

• Inhalation: At high concentrations: can irritate the nose and throat.
• Skin Contact: May cause mild irritation.
• Eye Contact: May cause slight irritation as a "foreign object". ...
• Ingestion: Not harmful.
