Titanium Dioxide

Titanium dioxide, also known as titania (IV) or titanium dioxide, is a natural formula for titanium oxide, titanium dioxide. When used as a pigment, it is called Titanium White, Pigment White 6 (PW6), or 77891 CI. Usually from ilmenite, rutile and anatase. It has a wide range of applications from food colors to sunscreen paints. When used as food coloring, E E171 quantity. World production in 2014 exceeded 9 million tons.

Occurrence

Titanium dioxide occurs in nature as well-known mineral rutile, anatase and brookite, and additionally as two high-pressure forms, monoclinic clinoptilolite-like forms and orthorhombic α-PbO 2 forms, most recently in the Bayerische Ries Mouth found. One of them, called akaogiite, should be considered an extremely rare mineral. It is mainly derived from ilmenite ore. This is the world’s most widely used titanium dioxide-containing ore. Rutile is the next most abundant, containing about 98% of the titanium dioxide in the ore. When heated at temperatures above 600-800 ° C (1,112-1,472 ° F), the metastable anatase and brookite phase are irreversibly converted to a balanced rutile phase.

Production

The production method depends on the raw material. The most common method for producing titanium dioxide is the use of mineral ilmenite. Ilmenite mixed with sulfuric acid. This reaction removes the iron oxide groups in ilmenite. By-product ferric sulfate crystals are filtered and filtered to produce only titanium salts in the digestion solution. The product is called synthetic rutile. This was further processed in a manner similar to rutile to give the titania product. Synthetic rutile and titanium slag are particularly useful in the production of titanium dioxide. The use of aluminum ore typically produces only pigmentary grade TiO2. Another method of producing synthetic rutile from ilmenite is the Becher method.

Rutile is the second most abundant ore. The rutile found in the host rock can not be extracted, so it is possible to mine rutile-containing deposits, implying a decrease in the availability of high-concentration ores. The crude titanium dioxide (in the form of rutile or synthetic rutile) is purified in the chlorination process by conversion to titanium tetrachloride. In this process, the ore (containing at least 70% of TiO2) is reduced with carbon and oxidized with chlorine to give titanium tetrachloride; The titanium tetrachloride is distilled and reoxidized in a pure oxygen flame or plasma at 1500-2000 K to obtain pure titanium dioxide while also regenerating the chlorine. The aluminum chloride is usually added to the process as a rutile promoter; the product is mostly anatase in its absence. The preferred starting material for the chlorination process is natural rutile, because of its high titanium dioxide content.

One method for producing titanium dioxide associated with nanotechnology is the synthesis of solvothermal titanium dioxide.

Applications

The most important areas of application are paints and varnishes, as well as paper and plastics, accounting for about 80% of the world’s consumption of titanium dioxide. Other pigment applications such as printing inks, fiber, rubber, cosmetics and food accounted for another 8%. The rest are used for other applications, such as the production of industrial pure titanium, glass and glass ceramics, electric ceramics, catalysts, electrical conductors and chemical intermediates. It is also in most red candy.
