Porosity in ceramics is usually avoided because porosity leads to a reduction in strength. However, there are a variety of applications where the use of porous materials is necessary.

The spectrum of applications ranges from catalyst carrier structures, filters, lightweight construction materials, energy adsorption or energy storage materials to bone replacement materials in the medical field. A variety of established and novel manufacturing methods are available. With these, a wide range of material properties, e.g. thermal conductivity, mechanical strength or damping, can be adjusted by using different materials. By saving material and thus resources, porous ceramic materials make an important contribution to CO2 savings and resource efficiency.
