Mixed oxide powder containing indium and tin, with a proportion of indium oxide of between 90 and 98 wt. % and a BET surface area of 40 to 120 m/g, which is in the form of aggregates having an average circumference of less than 500 nm, consists of at least 95% of an indium oxide phase and displays an oxygen content that is lower than the content that theoretically results from In2O3 and SnO2. It is produced by mixing a solution of an indium compound with a solution of a tin compound, atomising this mixture of solutions, pyrolysing the atomised mixture of solutions in a first zone of a reactor and in a second zone of the reactor, following pyrolysis, adding reducing gases to the pyrolysed mixture at one or more points in a quantity such that overall a reducing atmosphere is established in this second zone, and separating the resulting solid from the waste gases in a further, third zone, in which a reducing atmosphere likewise still prevails. It can be used for the production of transparent, electroconductive paints and coatings.

A claim is laid to a permeable composite, a process of production of the composite as well as the use of this composite. The composite essentially contains a perforated and permeable carrier, on and in or on or in which another component that essentially contains metallic compounds with elements from group III to VI of the periodic system is stabilized. Stabilization of the component on or in the carrier is carried out by heating a suspension consisting of the component suspended in a metallic oxide sol that has been applied onto or into or onto and into the carrier. In this way, it is possible to produce a permeable composite that is ideally suited for use in filtration and membrane technologies under very mild conditions either by heating for a short time or warming for a longer time.

The invention relates to a permeable composite material, a method for producing said composite material, and the use of the composite material. The inventive composite material contains essentially a porous, permeable support, another constituent having been solidified on and in or on or in said support. Said other constituent essentially contains metallic compounds with elements of the 3rd to the 6th main group. The constituent is solidified to, on or in the support by heating a suspension of the constituent suspended in a metal oxide sol applied on and in or on or in the support. The invention hereby provides a means of producing a permeable composite material in very mild conditions, either by heating strongly for a short period or by heating more moderately for a longer period. The resulting permeable composite material is excellently suited to applications in filtration and membrane technology.
