  The invention relates to a solid material (primary drying product) containing alkali metal silicate with a modulus (molar ratio of SiO.sub.2 to M.sub.2 O, M=alkali metal) of 0.8 to 4 in homogeneous admixture with other inorganic and/or organic useful materials and/or auxiliaries, which has been dried from a finely sprayed aqueous preparation of mixtures of the alkali metal silicates and the inorganic and/or organic useful materials and/or auxiliaries by means of a hot gas stream. The solid material according to the invention is characterized in that, as a primary drying product in homogeneous admixture with the alkali metal silicate, it contains at least 10% by weight of water-soluble inorganic and/or organic salts, has apparent densities of at least 150 g/l, possesses a microporous absorbent internal structure and has been dried with superheated steam as the hot gas stream. The invention also relates in particular to detergent builder systems based on multicomponent systems containing this overdried alkali metal silicate and to their use for subsequent impregnation with other free-flowing useful materials and mixtures thereof from the field of detergents and to the detergents obtained.

  The invention relates to sodium silicates with a modulus (molar ratio of SiO.sub.2 to Na.sub.2 O) of 1.3 to 4 in the form of a fine-particle solid in shard-like form or compounds containing these silicates with the ability to reduce incrustation when used as a builder component in detergents. These useful materials are distinguished in particular by the fact that they are in the form of an X-ray amorphous overdried material (primary drying product) with water contents below 15% by weight and apparent densities of the non-compacted solid granules of 500 g/l or lower which has been produced by drying of a water-containing sodium silicate preparation using a hot gas phase as the drying medium and/or by heating of a spray-dried sodium silicate with water contents of at least 15% by weight at temperatures of 120.degree.to 450.degree. C., if necessary accompanied or followed by the application of forces to produce the shard-like structure. The invention also relates to multicomponent mixtures from the field of solid detergents or multicomponent compounds suitable for this field of application which are characterized by the presence of the sodium silicates defined above.
