(57) [Summary] [Purpose] The long-term stability of an aqueous suspension containing fine solid particles, a dispersant and, if necessary, an organic polymer binder and, if necessary, a softening agent, was determined by Improve by preventing agglomeration. In the production of a suspension, the solid particles are washed in water before the production of the suspension; the anionic compounds are especially sulfates, carbonates, iodates, chromates, oxalates, Adding in the form of citrate and / or tartrate; producing a suspension and / or storing the finished suspension in a CO 2 -free gaseous atmosphere; producing a suspension, The finished suspension is stored at a temperature below 20 ° C., preferably below 15 ° C .; additional dispersant is added to the suspension, reaggregation of solid particles in the suspension has not yet begun or has begun A method for producing an aqueous suspension, wherein the steps added at the time of carrying out are individually or combined. |
