Porous and dense extrudates.

Fraunhofer IKTS has available the complete technological line for manufacturing silicate and oxide ceramic products from the processing of raw materials to the finishing and packaging of work pieces. For developing and manufacturing these products, an extensive know-how exists, which makes it possible to develop materials and structures for complex and demanding processes, thereby accommodating the required operational criteria. Special emphasis is placed on the development of defined porous materials and the specific pore formation of ceramic materials with different pore structures. Numerous projects were conducted regarding the development of porous structures for all sorts of application fields and then transferred into industrial manufacturing.
