Titanium dioxide, also known as titanium(IV) oxide or Titania, is the naturally occurring oxide of, chemical formula TiO2. When used as a pigment, it is called titanium white, Pigment White 6 (PW6), or CI 77891. Generally, it is sourced from ilmenite, rutile, and anatase. It has a wide range of applications, including paint, sunscreen, and food coloring. When used as a food coloring, it has E number E171. Titanium dioxide occurs in nature as the well-known minerals rutile, anatase and brookite, and additionally, as two high-pressure forms, a monoclinic baddeleyite-like form and an orthorhombic α-PbO2-like form, both found recently at the Ries crater in Bavaria. One of these is known as aragonite is an extremely rare mineral. It is mainly sourced from ilmenite ore. This is the most widespread form of titanium dioxide-bearing ore around the world. Rutile is the next most abundant and contains around 98% titanium dioxide in the ore. The metastable anatase and brookite phases convert irreversibly to the equilibrium rutile phase upon heating above temperatures in the range 600–800 °C.
Titanium dioxide has eight modifications – in addition to rutile, anatase, and brookite, three metastable phases can be produced synthetically (monoclinic, tetragonal and orthorhombic), and five high-pressure forms (α-PbO2-like, baddeleyite-like, cotunnite-like, orthorhombic OI, and cubic phases) also exist.
By Hexaresearch Report The globalis expected to reach USD 27.49 billion by 2024 owing to the increasing demand for titanium dioxide in paper, paint & coating, cosmetics, and plastic industries. In 2014, DuPont titanium technologies started a manufacturing facility in Alamira, Mexico having a capacity of 200,000 tons/year which will help in fulfilling the demand worldwide.
Rising demand for lightweight automobiles is expected to play a vital role in the growth of the global titanium dioxide market. Materials such as polycarbonates are used in the manufacturing of lightweight automotive which have low scratch resistance value. Also, the product is used in various industries such as chemical intermediates, fiber, technical titanium, inks for printer and rubber.
Keeping these driving factors in mind, companies are ramping up their production capacity. In 2015, PPG International entered in a partnership agreement with Henan Billions Chemicals Co. LTD. to set up a new manufacturing unit for titanium dioxide which is expected to produce 100,000 metric tons per year to expand its footprint in the Asia Pacific. Companies such as Argex Titanium are using unique patented CTL process which involves low-cost feedstock material and solvent extraction method to produce a high-quality product.
Also, companies are focusing on increasing the applications of titanium dioxide int water treatment using techniques such as photocatalysis, in which titanium dioxide is used to speed up the solar disinfection process.
A plastic industry was the second largest segment due to the increasing applications as an excellent thermal stabilizer. In 2016 plastics segment contributed 23.2% in terms of revenue and is expected to grow with a positive CAGR during the forecast period.
