High-Temperature Membranes and Storage Materials

Group

Oxygen storage material coated with catalyst.

Membrane tubes and ceramic honeycombs.

The working group „High-Temperaure Membranes and Storage Materials“ deals with ceramic shaping of special mixed oxides, with coating of ceramic components and with the development of processes and systems based thereof. Suitable manufacturing technologies aimed for shaping and coating will be permanently improved. Ceramic components like membranes, storage materials and catalysts can be optimized regarding special properties corresponding to the application aimed, e.g. concerning geometry, layer thickness, porosity, cell density. A manufacturing of ceramic components based on special materials for pre-industrial pilot plants is offered.
