To improve the compressive strength of moldings made of titanium dioxide with an average grain size d¶50¶ of 0.01 to 50 mm, these are each composed of primary crystallites of titanium dioxide of the anatase modification and have a specific surface area of 20 to 150 m 2 / g, a pore volume of 0.1 to 0.45 cm · 3 · / g and a pore diameter of 100 to 300 DOLLAR I1. |
