Abstract

Titanium-aluminium mixed oxide powder with a proportion of aluminium oxide of less than 1 wt. % or a proportion of titanium dioxide of less than 5 wt. %, wherein the sum of the proportions of titanium dioxide and aluminium oxide is at least 99.7 wt. %. It is produced by transferring a vaporous starting compound of the quantitatively greater component of the mixed oxide into a mixing chamber by means of primary air and a vaporous starting compound of the quantitatively smaller component of the mixed oxide by means of an inert gas, and burning the mixture mixed with hydrogen in a mixing chamber into a reaction chamber. It can be used as a catalyst support.
