FIELD: chemistry.
SUBSTANCE: invention can be used in the chemical industry to produce fillers. Method for producing an aqueous suspension of precipitated calcium carbonate comprises mixing water, a material containing calcium oxide, at least one water-soluble polymer with a molecular weight Mw in the range of 200 to 6,500 g/mol and at least one quenching additive. Resulting lime milk is carbonized to form an aqueous suspension of precipitated calcium carbonate.
EFFECT: present invention makes it possible to obtain a suspension of precipitated calcium carbonate with a high solids content without an additional concentration step.
