Abstract: front page image
(EN)Disclosed herein are slurries comprising at least one particulate inorganic material dispersed in an aqueous medium, at least one anionic polymeric dispersant in a solids content ranging from 0.1% to 3% by weight, wherein the at least one anionic polymeric dispersant is partially neutralized by at least one monovalent neutralizing agent, and at least one inorganic dispersant in an amount ranging from 0.3% to 5% by weight relative to the total weight of the inorganic solids in the slurry. Also disclosed are methods of making such slurries and products comprising or made from such slurries.
