FIELD: chemistry.
SUBSTANCE: invention can be used in paper and paint industry, in construction when making concrete and sealants, as well as in chemistry when producing plastics. An aqueous suspension contains natural ground calcium carbonate, wherein the percentage content by mass (P5) of particles with a diameter smaller than 5.0 mcm is 98.5-90%, the percentage content by mass (P2) of particles with a diameter smaller than 2.0 mcm is 96-80%, and the ratio P2/P5 is 0.98-0.85 and the content of dry substance in the suspension is higher than 78 wt %.
EFFECT: with high content of dry substance, the suspension has viscosity which is acceptable for making paper, including glossy paper, and does not require further dilution.
