Sachtleben Pigments
Patents Titanium Dioxide
U.S. 8,182,602 B2
Sachtleben Pigments has been granted a
patent for a method of preparing a well-dispersable, rutile-structured, microcrystalline titanium dioxide product having a
crystal size of less than 60 nm from a TiO2
starting material, the method is comprised
of the (A) stages of treating a TiO2 oxide
starting material to convert it into TiO2 so
that (A1) the starting material is treated
with a base to have an alkaline pH value;
(A2) a precipitate obtained from stage A1
is treated with hydrochloric acid so that a
final hydrochloric acid content is adjusted
to 8 to 35 g/l; (A3) the precipitate obtained
from stage A2 is neutralized into slurry to
a pH value of 4.0 to 6.0; (A4) the neutralized slurry obtained from stage A3 is
primed with a pretreatment chemical; (A5)
the primed slurry obtained from stage A4
is calcinated; and (B) further treating the
TiO2 obtained from stage A to convert it
into a TiO2 end product.
