Titanium dioxide is usually associated with iron, either as ilmenite or leuxocene ores.
Titanium dioxide pigments are insoluble in coating vehicles in which they are dispersed; accordingly, performance properties (chemical, photochemical and physical characteristics) are determined principally by the particle size of the pigment and the chemical composition of its surface.
Aside from its excellent pigmentary properties, titanium dioxide, as a chemical, has dielectric properties, high ultraviolet absorption and high stability, which allows it to be used in specialty applications, such as electro-ceramics and glass.

 Titanium Dioxide Whites - history
Although the titanium pigment, titanium dioxide was discovered in 1821, it was not until 1916 that modern technology had progressed to the point where it could be mass produced.
The masstone of titanium white is neither warm nor cool and lies somewhere between lead white and zinc white, in that respect.
