Abstract: Production of open-celled inorganic sintered foam products comprises (a) converting a dross material made of sinterable inorganic powder, a vaporisable material and optionally a material forming a propellent gas, in a foaming stage with release of the propellent into a foamed product, (b) treating the foamed product removing the flowability of the dross material forming an open-pored intermediate body, where steps (a) and (b) are carried out simultaneously, (c) removing material from the intermediate body forming a green foamed body to the foam product. Also claimed is a porous body made of sintered inorganic particles of 0.1-50 mu m. size, and having a pore volume of 50-95%, a surface area of 0.01-1 m /g. and irregular pores.
