What is Titanium DiOxide?
Titanium dioxide, also known as titanium(IV) oxide or titania, is the naturally occurring oxide of titanium with the chemical formula TiO2.
When used as a pigment, titanium white is referred to as Pigment White 6 (PW6) or CI 77891. It is usually obtained from ilmenite, rutile and anatase. It has a wide range of applications such as paint, sunscreen and food coloring. When used as a food dye, its E number is E171.
Titanium dioxide occurs in nature as the minerals rutile and anatase.
How is Titanium DiOxide produced?
The production method depends on the raw material. The most common mineral source is ilmenite. Abundant rutile mineral sand can also be treated by chloride or other processes. Ilmenite is converted to pigment grade titanium dioxide by the sulfate process or the chloride process. Both the sulfate and chloride processes produce the titanium dioxide pigment in rutile crystal form, but the Sulfate Process can be tuned to produce the anatase form. The softer anatase is used in fiber and paper applications.
Plants using the sulfate process need ilmenite concentrate (% 45-60 TiO2) or pre-treated raw materials as a suitable source of titanium. In the sulfate process, ilmenite is treated with sulfuric acid to extract iron(II) sulfate pentahydrate. The resulting synthetic rutile is processed to the specifications of the end user, i.e. pigment grade or otherwise. Another method for the production of synthetic rutile from ilmenite, the Becher Process, first oxidizes ilmenite as a means to separate the iron component.
An alternative process, known as the chloride process, converts ilmenite or other titanium sources through reaction with elemental chlorine to titanium tetrachloride, which is then purified by distillation and reacted with oxygen to regenerate chlorine and produce titanium dioxide. Titanium dioxide pigment can also be produced from higher titanium content raw materials such as slag, rutile and leukoxene, which have been cured through a chloride acid process.

What are the usage areas (processes) of Titanium DiOxide?
- En önemli uygulama alanları, dünyadaki titanyum dioksit tüketiminin yaklaşık%80’ini oluşturan boya ve verniklerin yanı sıra kağıt ve plastiklerdir.
- Other pigment applications such as printing inks, fibers, rubber, cosmetics and food also have a share of %8.
- Technical pure titanium is used in other applications such as the manufacture of glass and glass ceramics, electrical ceramics, metal patinas, catalysts, electrical conductors, and chemical intermediates.
- First mass produced in 1916, titanium dioxide is the most widely used white pigment because of its brilliance and very high refractive index.
- TiO2 is also an effective opacifier in powder form, where it is used as a pigment to provide whiteness and opacity to products such as paints, coatings, plastics, papers, inks, foods, pharmaceuticals (i.e. pills and tablets) and most toothpastes.
- Left as a thin film, its refractive index and color make it an excellent reflective optical coating for dielectric mirrors; It is also used in the production of decorative thin films.
- Titanium dioxide pigment is used in cosmetics and skin care products, sunscreens.
- It protects the skin from the harmful effects of UVA and UVB rays and does not irritate the skin.
- In ceramic glazes, titanium dioxide acts as an opacifier and nucleates crystal formation.
- It is used as a tattoo ink and in bloodstone.
