Abstract
Stable, translucent or transparent titanium dioxide sols comprising amorphous titanium dioxide and an organic peptizing agent are provided that are useful in particulate binding applications. Also provided are methods for preparing the inventive sols. The inventive sols are prepared from titanium dioxide precursors including organotitanium compounds and water-soluble titanium salts that are treated to precipitate amorphous titanium dioxide. The amorphous titanium dioxide is re-dispersed and peptized to form a translucent or transparent mixture. The inventive sols are stable for an extended period of time.
