Stable chloride process anatase slurries

摘要

Process for producing aqueous slurries of chloride process anatase titanium dioxide pigment by adding to the slurry from 0.03 to 0.45% by weight of sodium aluminate or aluminum trichloride, calculated as Al2O3 and based on the weight of the titanium dioxide pigment. The resulting slurries retain relatively low viscosity for at least one day.
