Used primarily in the production of titanium metal and titanium dioxide pigment. It serves as a key intermediate in the Kroll process, where it is reduced with magnesium or sodium to produce metallic titanium for aerospace and industrial applications. In pigment manufacturing, titanium tetrachloride is oxidized to form titanium dioxide, a white pigment used in paints, coatings, plastics, paper, and cosmetics due to its brightness, opacity, and light-reflecting properties. It is also used in the production of smoke screens and fog, as it reacts vigorously with moisture in air to produce dense white fumes. Additionally, it acts as a key component in Ziegler-Natta catalysts for the synthesis of various polymers, such as polyethylene and polypropylene, and as a precursor in other organic synthesis reactions. It is further employed in surface coating processes to enhance corrosion resistance, in the electronics industry for manufacturing certain semiconductors, and in nanotechnology research for advanced materials.
