摘要

ABSTRACT OF THE DISCLOSUREAqueous suspensions of water-insoluble, calclum-bindingaluminosllicates with an improved stability against settling com-prising at least 20% by weight of at least one finely-divided,water-insoluble silicate compound having a calclum-binding powerof at least 50 mg CaO/gm of anhydrous active substance and havingthe formula, combined water not shownwhere 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 yis a number from o.8 to 6, and at least 0.5? by weight of an in-organic water-insoluble, but water-swellable silicate with alaminated structure.-A-
