摘要： What is described is a slurry comprising (a) at least 10% by weight of at least one sheet silicate, based on the total weight of the slurry; (b) an aqueous suspension medium and (c) a dispersing aid selected from at least one polyethylene glycol having a mean molecular weight of less than 90 000 and/or at least one polyacrylic acid in free acid form. Also described is a process for producing the slurry and the preferred used thereof.
