Abstract: A powdered catalyst material on a titanium oxide basis. The powdered catalyst material includes a combined content of at least 90 wt.-% of a hydrated titanium oxide having the general formula TiO(2-x)(OH)2x, with 0<x?1, (calculated as TiO2), and a silicon dioxide and hydrated precursors of the silicon dioxide (calculated as SiO2). A weight ratio of TiO2/SiO2, determined for TiO2 and SiO2 respectively, is at least 3 and less than 30. The wt.-% is based on a total weight of the catalyst material after the catalyst material has been dried at 105° C. for at least 2 hours. The powdered catalyst material has a specific surface area of >300 m2/g and an isoelectric point of from 4.0 to 7.0.

Abstract: A TiO2-based catalyst precursor material in powder form includes TiO2 particles with the formula TiO(2-x)(OH)2x (x=0-1). The particles are coated with one or more auxiliary shaping agents and after coating and drying have a specific surface area of at least 150 m2/g. The material has a content of 1) 50-99.5% by weight of the titanium-oxygen compound with the general formula TiO(2-x)(OH)2x, wherein x=0 to 1, or mixtures thereof, wherein the crystalline phases of the titanium-oxygen compound are in the anatase form, and 2) 0.5-50% by weight of an auxiliary shaping agent or mixtures thereof, which evaporates, sublimates and/or decomposes upon heating to temperatures below the transformation temperature from anatase to rutile, wherein the % by weight are relative to the total weight of the dried catalyst precursor material.

Abstract: A method for producing surface-treated particles includes surface treatment of titanium dioxide, barium sulfate, zinc sulfide or lithopone particles, and to mixtures of the particles with alkoxylated siloxanes and phthalate-free plasticizers for improving dispersion in plastics.
