Cellular Ceramics: New Fabrication Methods and Applications

The requirements with respect to porosity, pore sizes, permeability,
thermal and mechanical properties vary so much that they can not be
matched by one fabrication method, but diverse methods have to be
applied in order to obtain the desired properties. The process
technologies selected are the following:

  • foaming by expandable space holders to obtain a fine pore structure
  • foaming by expandable polystyrene to obtain a coarse pore structure
  • native bonding of hollow spheres.
