Abstract

The invention relates to an ion-conducting composite which is permeable to matter, to a method for producing an ion-conducing composite which is permeable to matter, and to the use of this composite in various processes. Membranes or ion-conducting materials are used for various chemical and physical process, e.g., electrolysis, electrodialysis. The membranes used are often polymer-based. These polymers are relatively non-resistant to solvents and high temperatures. Therefore, the aim of the invention is to provide an ion-conducting composite. The inventive composite consists of inorganic constituents or at least mainly of inorganic constituents, and is characterised in that is very stable in relation to acids and high temperatures. According to the invention, ion-conducting materials or materials which will be ion-conducting after an additional treatment are added to a composite which is permeable to matter during production. Alternatively, the finished composite is treated with said materials.
