Abstract

The invention concerns an aqueous suspension of precipitated calcium carbonate particles, said suspension having a pH stabilised at a value less than 9, said calcium carbonate particles containing an agent for obtaining a positive zeta potential of the calcium carbonate particles, the agent for obtaining a positive zeta potential being a substance causing Ca<++> ions to dissolve.
