<p>Aqueous suspensions of water-insoluble, calclum-binding aluminosllicates with an improved stability against settling comprising at least 20% by weight of at least one finely-divided, water-insoluble silicate compound having a calclum-binding power of at least 50 mg CaO/gm of anhydrous active substance and having the formula, combined water not shown 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 o.8 to 6, and at least 0.5? by weight of an inorganic water-insoluble, but water-swellable silicate with a laminated structure. -A-</p> |
