The present invention relates to a process for preparing TiO/SiOmixed oxides or the hydrates and/or oxide hydrates thereof comprised of 0.5 to 95 wt % SiOand the balance as TiO, each referring to the completely calcined product, by using titanium alcoholates and aqueous silica sol. Moreover, the invention relates to the use of these mixed oxides as catalyst carriers.

The invention relates to a process for the preparation of a high-purity, thermally stable catalyst carrier based on aluminosilicate with 0.5 to 50% by weight SiO.sub.2 by mixing an aluminum compound with a silicic acid compound in an aqueous medium, and subsequently drying or calcining the product obtained. The aluminum component used is a C.sub.2 to C.sub.20+ aluminum alkoxide hydrolyzed with water and purified by means of ion exchangers. Simultaneously or subsequently orthosilicic acid purified by means of ion exchangers is added to the aluminum compound.
