Ink and paper pigments

The more important compound, from the industrial point of view, is the titanium dioxide that, because of its extreme whiteness and high reflectance, is widely used as pigment in the production of inks, lacquers, enamels, paper, rubber, textile, plastics, ceramic and cosmetics. When crystallized, rutile is also used in the production of artificial precious stones that imitate diamond. Among the remaining compounds the titanium (IV) sulfate, used in the production of the dioxide, and the titanium (III) sulfate (with a blue color), which is a powerful oxydizer, deserve special reference. The titanium (IV) halogens are used in the production of the so-called smoke curtains; the salts of organic acids are used as mordant for coloring and also in tannery.

The titanates, especially the iron one, are important raw materials for obtaining the metal; the barium titanate possesses piezoelectric properties. The metal is widely used in the production of equipment that demands lightness combined with mechanical resistance. It is mainly used in the military and aeronautical industries (helixes, turbines, reactors, missiles, etc.) and in photographic cameras. In most of the cases it is used in the form of alloys with other metals as the aluminum, iron, manganese, chromium, molybdenum and vanadium. These applications take over 90% of the total production of titanium; the remaining is destined to the manufacture of equipment for the chemical industry.
