Editing Titanium tetrachloride (section)

===Production of titanium dioxide===
Around 90% of the {{chem2|TiCl4}} production is used to make the pigment [[titanium dioxide]] ({{chem2|TiO2}}). The conversion involves [[hydrolysis]] of {{chem2|TiCl4}}, a process that forms [[hydrogen chloride]]:<ref name=Ull>{{cite encyclopedia|first=Hans G. |last=Völz |display-authors=etal |title=Inorganic Pigments|encyclopedia=Ullmann's Encyclopedia of Industrial Chemistry |publisher=Wiley-VCH |location=Weinheim |date=2006 |doi=10.1002/14356007.n20_n04|chapter=Pigments, Inorganic |isbn=978-3-527-30673-2 }}</ref>

:{{chem2|TiCl4 + 2 H2O → TiO2 + 4 HCl}}

In some cases, {{chem2|TiCl4}} is oxidised directly with [[oxygen]]:

:{{chem2|TiCl4 + O2 → TiO2 + 2 Cl2}}
