The causticizing process converts green liquor into white liquor in the kraft pulp mill, producing calcium carbonate as a byproduct. The conventional calcium carbonate (CCC) includes nonuniform particles with large diams., which cause severe abrasion of plastic wire on paper machines and poor opacity of paper when it is used as a paper filler.

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 ...

When calcium carbonate reacts with water that has dissolved carbon dioxide, it forms a calcium bicarbonate. As new cold water with dissolved calcium carbonate is added and heated, the process continues. In this process, the CO 2 gas is removed repeatedly, and the carbonate concentration increases, and thus more calcium carbonate precipitates ...
