Classic processes such as cold isostatic pressing, extrusion, slip casting or wet pressing are available for shaping ceramic and powder metallurgical green bodies in addition to 3D printing. Special measuring and simulation methods have been developed for drying (see Drying). The quality of green bodies is examined using special in-house procedures and methods – including dual-energy computer tomography (see Non-destructive test procedures). The thermal processes on the green bodies are employed in different electrically or gas-fired furnaces. Inert gas, oxide or reducing gas atmospheres as well as a vacuum or over-pressure can be implemented here. A well-aimed optimization of the parameters in the heat treatment processes is carried out by special ThermoOptical measurement methods (TOM). Melt infiltration processes are used for the manufacture of composites (see Melt infiltration). Additively manufactured components in particular have a high potential to deliver near net-shape components with optimized heat treatment. Should finishing of functional surfaces be necessary, a computer-controlled five-axis machining center is available. Components with complex geometries can be built up from simple components using high-temperature joining processes. The material and component properties are evaluated using non-destructive methods, material testing methods and microstructure analyses (see Characterization).
One application focus is on high-temperature materials: e.g. lightweight refractory equipment, high-temperature insulation made of foam ceramics, sensor and furnace materials as well as high-temperature joining. We also have experience in the development of electro ceramics, e.g. for actuators, varistors, insulators and heat sinks. Furthermore, cutting and structural materials are developed.
