Titanium dioxide, also known as titanium(IV) oxide or titania, is the naturally occurring oxide of titanium, chemical formula TiO2. When used as pigment, it is called titanium white, Pigment White 6 (PW6), orCI77891. Generally it is sourced from ilmenite,rutile and anatase.. It has a wide range of applications, from paint to sunscreen to food coloring.When used as a food coloring, it has Enumber E171. World production in 2014 exceeded 9 million metric tons.
Pure TiO2 is a fine, white powder and is the brightest, whitest pigment available. Highly refractive, ultraviolet absorbing, non-toxic and inert, TiO2 has been used for many years (over 90) in a vast range of industrial applications and consumer goods to impart whiteness and opacity to paints, printing inks; and tio2 for plastics, textiles, ceramics, construction materials, cosmetics, food, pharmaceuticals, etc.
TiO2 is produced primarily in the pigmentary form (over 98% of total production) making use of its excellent light-scattering properties in the wide range of applications that require white opacity and brightness.
TiO2 is also produced as an ultrafine (nanomaterial) product when different properties such as transparency and maximum UV light absorption are required, such as in cosmetic sunscreens. Ultrafine TiO2 products are also used in a range of environmental applications such as catalysts supports in the automotive industry to remove harmful exhaust gas emissions, and in power stations to remove nitrous oxides (NOx). Approximately 1-2% of the total production of TiO2 is in this ultrafine form.
