Abstract
Poorly crystallized or amorphous TiO.sub.2 particulates having a mean particle size greater than 20 nm are prepared by thermally hydrolyzing a titanium compound in solution, in the presence of at least one carboxylic acid containing a hydroxyl and/or amino group, or an organophosphoric acid; the TiO.sub.2 particulates thus produced are readily molded/extruded into useful shaped articles, e.g., catalysts or catalyst supports, having good porosity and mechanical properties.
