    摘要: 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.

    摘要: A tablet composition containing 2% to 100% by weight of amorphous crystalline or partly crystalline layer-form sodium silicates corresponding to the formula Na.sub.2 Si.sub.x --O.sub.2x+1.yH.sub.2 O wherein x is a number of 1.9 to 4 and y is a number of 0 to 20, with the proviso that the tablet composition only contains water in a quantity such that the maximum theoretical water-binding capacity of the components of the composition is not exceeded.
