Abstract
Binary mixtures of polyacrylates and sodium silicates are used as deflocculating agents for kaolin slurries to ensure pumpability and pourability of the slurry. An example of a binary mixture is a mixture of 67% by weight sodium polyacrylate having a weight average molecular weight of 4,200 and 33% by weight of sodium silicate on a dry solids basis.
