用0.5M H3 PO 4滴定沸腾的Ca（OH）2水悬浮液制备的羟基磷灰石（Ca 3 O 4 OH（OHAp））在三元体系Ca（OH）2-H3 PO 4-H2O中的溶解度等温线在5、15、25和37 ℃下用稀H3 PO 4溶液平衡，pH范围为3.7 -6.7。由41个实验点通过广义最小二乘法确定的作为温度的函数的溶度积ε n由下式给出：
Solubility isotherms of hydroxy apatite, C a s ^ O ^ O H (OHAp), prepared by titrating a boiling aqueous suspension of Ca(0H)2 with 0.5 M H3PO4, were determined in the ternary system Ca(0H)2-H3P04-H20 at 5, 15, 25 , and 37 °C in the pH range 3 .7-6.7 by equilibration with dilute H 3 P0 4 solutions. The solubility product £ „ determined as a function of temperature by a generalized least-squares procedure from 41 experimental points, is given by the equation
