摘要：
A process for the precipitation of discrete prismatic calcium carbonate particles by carbonation of aqueous calcium hydroxide containing a saccharide or polysaccharide or a saccaride or polysaccharide and a metal ion at temperatures of from about 8.degree. C. to about 64.degree. C. is disclosed. The resulting product has specific surface areas between about 10 m.sup.2 /g and about 120 m.sup.2 /g and is useful in paints, plastics, paper coating, paper filling, and pharmaceutical applications.
