  • Flame-hydrolytically produced titanium dioxide powder
    Patent number: 7686881
    Abstract: Flame-hydrolytically produced titanium dioxide powder that is present in the form of aggregates of primary particles, and has a BET surface of 20 to 200 m²/g, a half width (HW) [nm] of the primary particle distribution of HW = a×BETf where a = 670×10?9 m³/g and ?1.3 ≤ f ≤ ?1.0 and the proportion of particles with a diameter of more than 45 &mgr;m lies in a range from 0.0001 to 0.05 wt. %. The powder is produced by a process in which a titanium halide is vapourised at temperatures of less than 200°C.
    Type: Grant
