Abstract

Solubility of human dental enamel in H3PO4 was studied in the pH range of 4.5 to 7.6. Thermodynamic solubility of the enamel mineral was calculated in terms of the ion activity product, (Ca2+)5(PO43-)3(OH-), for hydroxyapatite. The solubility product varied from 7.2 times 10(-53) to 6.4 times 10(-58) mol9 liter-9 depending on the cumulative amount of the dissolution of the solid in a series of repetitive sequences of solubility experiments.

摘要

在4.5至7.6的pH范围内研究了人牙釉质在磷酸中的溶解度。根据羟基磷灰石的离子活度积（Ca2+）5（PO43-）3（OH-）计算了牙釉质矿物质的热力学溶解度。在一系列重复性溶解度实验中，根据固体溶解的累积量，溶度积在7.2×10^(-53)至6.4×10^(-58) mol^9 liter^(-9)之间变化。
