Composites comprising at least one hollow fibre of oxygen-transporting ceramic material, which is a ceramic material which conducts oxygen anions and electrons or a combination of ceramic material which conducts oxygen anions and a ceramic or nonceramic material which conducts electrons, with the outer surface of the hollow fibre being in contact with the outer surface of the same hollow fibre or another hollow fibre and the contact points being joined by sintering, are described. Further composites comprise at least one hollow fibre of oxygen-transporting ceramic material which is a ceramic material which conducts oxygen anions and electrons or a combination of ceramic material which conducts oxygen anions and ceramic or nonceramic material which conducts electrons and a connection element for the introduction or discharge of fluids at at least one end face, with hollow fibres and connection element being joined. The composites can be used for isolating oxygen from oxygen-containing gas mixtures or for carrying out oxidation reactions.
