  • TRANSPARENT, STABLE TITANIUM DIOXIDE SOLS
    Publication number: 20110183838
    Abstract: A method of preparing stable, transparent photocatalytic titanium dioxide sots is disclosed which involves thermal treatment of a suspension of amorphous titanium dioxide in the presence of certain alpha-hydroxy acids. The sots comprise titanium dioxide particles in the anatase form having a crystallite size less than about 10 nm and exhibit excellent stability and transparency at basic, neutral, and acid pH.
    Type: Application
    Filed: April 1, 2011
    Publication date: July 28, 2011

  • Colloidal titanium dioxide sols
    Patent number: 7820724
    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.
