摘要：

The mechanisms of the formation and transformation of calcium carbonates and the inhibition by the phosphorus containing compounds were studied. Supersaturated solutions form the unstable polymorph. amorphous calcium carbonate, at first, followed by the transformation to the metastable polymorph which finally transforms to stable form, calcite. Transformation proceeds by a mechanism of recrystallization. The growth and transformation is strongly inhibited by a phosphorus containing compounds. Details of the adsorption mechanism were reported. The zeta potentials of calcium carbonates were determined at various solution conditions.
