A process for producing open-celled, inorganic sintered foam products which comprises: a. converting slip material comprising sinterable inorganic powder, a fluid, vaporizable material which makes this slip material capable of flow and, if desired, a material forming blowing gas into a foamed product in a foaming step with liberation of the blowing gas, b. subjecting this foamed product to a treatment which essentially makes the slip material incapable of flow and forms an open-pored intermediate body, with the steps a. and b. being able to proceed essentially simultaneously, c. removing material remaining from the fluid material and any further material from the intermediate body to form a green foam body, and d. sintering the green foam body to form the open-celled, inorganic sintered foam product.
