Abstract

Способ синтеза высокодисперсного карбоната кальция, включающий взаимодействие гидроксида кальция с диоксидом углерода в водной среде, отличающийся тем, что перед взаимодействием с диоксидом углерода гидроксид кальция диспергируют в растворе, содержащем или соли аммония из группы- хлорид аммония, нитрат аммония, или сахарозу в концентрации от 4% до 30% и поверхностно- активные вещества(ПАВ) в количестве от 0,01% до 5%, считая на массу исходного гидроксида кальция. A method for the synthesis of finely divided calcium carbonate, comprising reacting calcium hydroxide with carbon dioxide in an aqueous medium, characterized in that before reacting with carbon dioxide, calcium hydroxide is dispersed in a solution containing either ammonium salts from the group ammonium chloride, ammonium nitrate, or sucrose in a concentration of 4% to 30% and surfactants in an amount of 0.01% to 5%, based on the weight of the initial calcium hydroxide.
