FIELD: chemistry.
SUBSTANCE: suspension containing calcium carbonate is obtained by adding one or more zirconium compounds and possibly one or more other additives which do not contain phosphate, acting as a dispersant and/or an additive which assists in grinding. Calcium carbonate in dry form and/or in form of an aqueous dispersion or filtered residue is added an aqueous suspension and/or aqueous emulsion and/or aqueous solution containing one or more zirconium compounds. The zirconium compounds used is ammonium zirconium carbonate or calcium zirconium carbonate or mixture thereof.
EFFECT: invention enables to avoid the use of phosphate dispersants when preparing stable aqueous suspensions of calcium carbonate and increases content of solid substance in the suspension.
