Abstract
The present invention relates to polyoxometalate-coated alumina trihydrate dispersants prepared by combining a polyaluminum chloride having certain characteristics with alumina trihydrate particles. Such dispersants are useful for forming cationic alumina trihydrate slurries, which can be mixed with titanium dioxide to produce stable cationic slurry blends useful in paper, paper-board, and paint (coatings) applications. The dispersants are also useful for preparing cationic titanium dioxide slurries.
