Zusammenfassung:The present utility model discloses the method of preparing nano precipitated calcium carbonate. The method comprises the steps of preparing slaked lime slurry, bubbling with carbon dioxide gas, drying and screening to obtain a homogeneous nano precipitated calcium carbonate. The nano precipitated calcium carbonate has an average particle size ranging from 40-80 nm, high specific surface area and crystal structure of scalenohedral calcite particles. The present utility model provides a method of preparing high value products from limestone materials for wider range of industrial applications.
