Abstract

A process for producing silicate or silicate-containing builder granules having an apparent density of at least 600 g/l by compacting silicate materials having an apparent density of less than 500 g/l, a molar ratio of SiO.sub.2 to Na.sub.2 O of 1.3 to 4, and a water content of up to 15% by weight, wherein the silicate materials are X-ray amorphous and are present in the form of a fine particle solid having a flake structure.
