FIELD: chemistry.
SUBSTANCE: invention can be used in chemical industry. The method for synthesis of finely dispersed calcium carbonate involves reaction of calcium hydroxide with carbon dioxide in an aqueous medium. Before reacting with carbon dioxide, calcium hydroxide is dispersed in a solution containing either ammonium salts selected from a group comprising ammonium chloride, ammonium nitrate, or saccharose with concentration of 4-30% and surfactants in amount of 0.01-5% per mass of the starting calcium hydroxide.
EFFECT: invention enables to obtain finely dispersed calcium carbonate.
