Chloride process

Production of titanium (IV) oxide using processes (chloride process or sulphate process ), with a distinction from Chinese production

In the chloride process , rutile or TiO ₂ slag is converted into titanium tetrachloride at 800–1200 ° C with coke and chlorine . After purification by distillation, TiCl ₄ vapor is burned with oxygen to form titanium dioxide and chlorine gas (1000–1400 ° C):

${\displaystyle \mathrm {TiO_{2}+2\ C+2\ Cl_{2}\rightarrow TiCl_{4}+2\ CO} }$

${\displaystyle \mathrm {TiCl_{4}+O_{2}\rightarrow TiO_{2}+2\ Cl_{2}} }$

Titanium tetrachloride is also used in the manufacture of titanium.
