Titanium dioxide is the most used white pigment and provides whiteness and opacity for paints and coatings (including glazes), plastics and paper. It has many speciality uses. It is resistant to UV radiation and thus does not discolour over a long period of time and ultra pure and fine crystal titanium dioxide grades are being increasingly used ...

Production and processing. Pure titanium readily reacts with oxygen, and so much of the titanium found in nature appears as ore or "sponge", specifically rutile (TiO 2) or ilmenite (FeTiO 3). The Kroll process extracts TiO 2 from the ore through a reduction process in the presence of chlorine gas, which produces titanium tetrachloride (TiCl 4).

The Kroll Process was first introduced in 1938 and (combined with vacuum distillation) is still the most common method used to extract titanium metal from its ore.

Titanium Dioxide (TiO2) Production and Manufacturing Process. TiO2 is produced from either ilmenite, rutile or titanium slag. Titanium pigment is extracted by using either sulphuric acid (sulphate process) or chlorine (chloride route). The sulphate process employs simpler technology than the chloride route and can use lower grade, cheaper ores.

Titanium dioxide is also dubbed as the principal white pigment of commerce in the 20 th century, as it has become increasingly dominant over rival white pigments like lithopone, white lead, and zinc white. Discovered as far back as 1821, the titanium dioxide white pigment only started to be mass produced in 1916 in Norway for industrial purposes.
