Abstract
The present invention relates to a process for producing a foam ceramic comprising the steps: producing an aqueous suspension of a first mineral raw material; foaming the suspension with air while adding a foaming agent and a binder to form a light foam; mixing the light foam with a powder or slip of a second ceramic raw material to form a heavy foam; pouring the heavy foam into a mold; drying the molded heavy foam in the mold to form a solid foam; and firing the solid foam in the mold to form the foam ceramic.
