摘要：

The precipitation of calcium phosphates was studied by a method which allowed a desired supersaturation to be built up under well-defined conditions. Special attention was paid to the stage preceding the growth of nonstoichiometric apatitic crystals. Growth curves at pH 6.7, 7.4, and 8.5 and at 26 °C are presented. Analysis of these experimental data indicates octacalcium phosphate as an intermediate phase in the apatite formation process. Light scattering measurements suggest the formation process to be initiated by a heterogeneous nucleation step. © 1979 American Chemical Society.
