PROCESS FOR THE PREPARATION OF DISCRETE PARTICLES OF CALCIUMCARBONATE |
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 saccharide 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 m2/g and about 120 m2/g and is useful in paints, plastics, paper coating, paper filling, and pharmaceutical applications.</SD OAB>
