  • Composition of precipitated calcium carbonate, method of producing the same and the uses thereof
    Patent number: 11053642
    Abstract: Composition of precipitated calcium carbonate and method of producing the same and the uses of the composition. The composition comprises a plurality of essentially spherical granules having an average diameter of 1-50 um formed from primary precipitated calcium carbonate particles having an average diameter of 30 to 60 nm, capable of liberating at least a part of the primary particles by deagglomeration in aqueous suspension. The present compositions can be used for modifying binders of paints, printing inks, plastics, adhesives, sealants and surface sizes and pulp sizes. The invention further concerns a method for storing of precipitated calcium carbonate particles having an average diameter in the nanometer range.
