TITANDIOXID MIT ERHÖHTER SINTERAKTIVITÄT

摘要

The crystalline titanium dioxide powder has a aggregated primary particles form. The aggregated primary particles form has a Brunauer-Emmett-Teller surface area of 30-65 m 2>/g and a rutile content of 50-70%. An independent claim is also included for a method for preparing titanium dioxide powder, which involves introducing hydrogen, air or oxygen-enriched air into a mixing chamber, where a mixture of titanium tetrachloride vapour, hydrogen and primary air is subsequently ignited in a burner and the flame is burned into a reaction chamber, the solid is subsequently separated off from gaseous substances.
