The kinetics of growth of calcium phosphate on seed materials prepared from human tooth enamel has been studied at 25 degrees C and pH 7.40 in stable supersaturated solutions of calcium phosphate. The grown material was characterized chemically, by specific surface area (SSA) measurements and by subsequent dissolution experiments. The marked increase in SSA in the early stages of the precipitation reaction parallel the results obtained with synthetic hydroxyapatite seed crystals and the results of the dissolution experiments indicate a chemical composition close to that of octacalcium phosphate for this intermediate phase. At low supersaturation it is possible to avoid the formation of the precursor phase.
在25摄氏度和pH值为7.40的磷酸钙稳定过饱和溶液中，研究了磷酸钙在由人类牙釉质制备的晶种材料上的生长动力学。通过化学分析、比表面积（SSA）测量以及后续的溶解实验对生长的材料进行了表征。沉淀反应早期阶段SSA的显著增加与合成羟基磷灰石晶种晶体的结果相似，溶解实验结果表明该中间相的化学成分接近磷酸八钙。在低过饱和度下，可以避免前驱相的形成。
