Abstract. Hybrid calcium carbonate (HCC) is prepared by preflocculating calcium oxide and ground calcium carbonate (GCC) with ionic polymers, and by injecting carbon dioxide to the preflocculated flocs until termination of the reaction at neutral pH. When used in papermaking, HCC gave higher bulk, higher stiffness, and higher tensile strength ...

Similar binding of calcium ions is observed in the prenucleation stage. About 35% of added calcium ions are bound at pH = (∼4% carbonate ions in the buffer equilibrium), whereas ∼75% of added calcium ions are bound at pH = (∼25% carbonate ions in the buffer equilibrium). This shows that calcium binding during the prenucleation ...
