Sulfate (Sulfuric Acid) Method of TiO2 Production
The sulfate method was first implemented industrially in 1931 for
producing the anatase form of titanium dioxide, followed by the
rutile form in 1941. This process involves dissolving ilmenite
concentrate or titanium slag in sulfuric acid to create solutions
of titanium, iron, and other metal sulfates. Through a series of
controlled technological steps—including chemical reduction,
purification, precipitation, washing, and calcination—basic TiO2 with the desired particle size is formed. The crystal structure
(anatase or rutile) is determined during nucleation and
calcination.
Process Chemical Equations
FeTiO3 + 2H2SO4 → TiOSO4 + FeSO4 + 2H2O
TiOSO4 + H2O → TiO2 + H2SO4
TiOSO4 + H2O → TiO2 + H2SO4
