ABSTRACT:
Molded parts having high flexural strength, based on alkali silicates, can be produced by casting and/or press-molding and curing by heating from aqueous molding compositions which are prepared from an oxide mixture containing amorphous silicic acid and aluminum oxide, as well as, optionally, as an additional component, aqueous, amorphous, disperse-powdery silicic acid, dissolved SiO.sub.2, and alkali from alkali silicate solutions, optionally alkali hydroxide or its aqueous solutions and, if desired, fillers, by means of mixing under agitation. By addition of a blowing agent inorganic foamed products can be obtained.
