摘要: A slurry containing water, carbonate-containing pigment, and dispersant consisting of 25-70 % by weight of agglomerated carbonate-containing pigment, 0.1-1.0% by weight of a dispersant, the balance being water up to 100%, can be used advantageously in papermaking as well as in the paint and lacquer industry. In a novel process for agglomerating ultra-fine particles in slurries the slurry is subjected to heat treatment until the agglomeration is complete.
