摘要: Aqueous suspension of particles precipitated calcium carbonate meeting the following requirements: dp <= D50 q.dp where is mean diameter (nm), measured by Lea-Nurse method, (nm) for which 50 % distribution (measured sedimentation technique) smaller and greater, q a number between 1.0 20.0, comprising an additive chosen from nonionic compounds more than one carbon atom, content which, with respect to carbonate, greater 0.4 weight.
