通过微量分析钙、磷和砷饱和溶液中钙、磷和砷的含量，在37℃、pH 5.0到7.6的缓冲体系中，研究了羟基磷灰石及其砷同质异构体及其一系列固溶体在整个组成范围内的溶解度平衡。根据所测定的样品的离子产物，确定了它们的化学计量溶解，并计算了它们的溶液自由能。
The solubility equilibria of synthetic samples of hydroxylapatite, its arsenic isomorph, and a series of their solid solutions, spread over the entire compositional range, were investigated at 37 °C in the pH range 5.0 to 7.6 in buffered systems through microanalytical determinations of calcium, phosphorus, and arsenic in their saturated solutions. From the ionic products of the samples so determined their stoichiometric dissolution was established and their free energies of solution evaluated.
