Zusammenfassung:Aqueous suspensions of water-insoluble, calcium-binding aluminosilicates with an improved stability against settling comprising at least 20% by weight of at least one finely-divided, water-insoluble silicate compound having a calcium-binding power of at least 50 mg CaO/gm of anhydrous active substance and having the formula, combined water not shown (M2/nO)x . Me2O3 . (SiO2)y WHERE M is a cation of the valence n, exchangeable with calcium, x is a number of from 0.7 to 1.5, Me is aluminum or boron, and y is a number from 0.8 to 6, and at least 0.5% by weight of at least one organic dispersing agent as follows:
