GAS PHASE PRODUCTION OF COATED TITANIA

A flame spray pyrolysis process for the preparation of ultrafine titania particles coated with a smooth, homogeneous coating of one or more metal oxides is provided. The metal oxide coating is achieved by contacting the titania particles with a metal oxide precursor downstream of the titania formati...

More Information
Summary:A flame spray pyrolysis process for the preparation of ultrafine titania particles coated with a smooth, homogeneous coating of one or more metal oxides is provided. The metal oxide coating is achieved by contacting the titania particles with a metal oxide precursor downstream of the titania formation zone, after the titania particles have formed. The process provides titania particles with a high rutile content and a smooth and homogeneous coating of a metal oxide.
