12 Facts About Titanium dioxide

Molten titanium dioxide has a local structure in which each Ti is coordinated to, on average, about 5 oxygen atoms.

Titanium dioxide occurs in nature as the minerals rutile and anatase.

Titanium dioxide has twelve known polymorphs – in addition to rutile, anatase, brookite, akaogiite and riesite, three metastable phases can be produced synthetically, and four high-pressure forms exist:.

Titanium dioxide is found as a mineral in magmatic rocks and hydrothermal veins, as well as weathering rims on perovskite.

Major paint and coating company end users for pigment grade titanium dioxide include Akzo Nobel, PPG Industries, Sherwin Williams, BASF, Kansai Paints and Valspar.

Nanosized titanium dioxide is found in the majority of physical sunscreens because of its strong UV light absorbing capabilities and its resistance to discolouration under ultraviolet light.

Nano-scaled titanium dioxide particles are primarily used in sunscreen lotion because they scatter visible light much less than titanium dioxide pigments, and can give UV protection.

Titanium dioxide is produced in varying particle sizes which are both oil and water dispersible, and in certain grades for the cosmetic industry.

Interfaces between rutile and anatase are further considered to improve photocatalytic activity by facilitating charge carrier separation and as a result, biphasic titanium dioxide is often considered to possess enhanced functionality as a photocatalyst.

Titanium dioxide is mostly introduced into the environment as nanoparticles via wastewater treatment plants.

Cosmetic pigments including titanium dioxide enter the wastewater when the product is washed off into sinks after cosmetic use.

Titanium dioxide says that the titanium dioxide used by Dunkin' Brands and many other food producers is not a new material, and it is not a nanomaterial either.
