01 /Applications

Titanium Dioxide Production

Titanium tetrachloride serves as a primary feedstock for the chloride process, a major industrial method for manufacturing high-purity titanium dioxide pigment, widely used in paints, plastics, and paper.

Titanium Metal Production

It is a key intermediate in the Kroll process for the extraction and refining of titanium metal, valued for its high strength-to-weight ratio and corrosion resistance.

Catalysis and Chemical Synthesis

As a strong Lewis acid, titanium tetrachloride is utilised as a catalyst in Friedel-Crafts reactions and other organic syntheses, and as a reagent in the preparation of various titanium-containing compounds.

Vapor Deposition Precursors

Titanium tetrachloride is used as a precursor in chemical vapour deposition (CVD) and atomic layer deposition (ALD) for creating thin films of titanium compounds in semiconductor and materials science applications.
