摘要
通过测量粉体在水溶液中的Zeta电位和颗粒大小,研究了不同条件下羟基磷灰石水悬浮液的电动特性。结果表明,溶液的pH值以及引入的聚电解质不同均会使羟基磷灰石颗粒表面的荷电状态发生变化.进而导致粉体在水溶液中的分散状况发生变化。在碱性条件下添加适当的阴离子聚电解质有利于羟基磷灰石水悬浮液的稳定分散。
Electrokinetic behavior of aqueous hydroxyapatite (HAp) suspensions was studied by measuringzeta potential and effective particle size. Results indicated that such parameters as pH value and type of polyelec-trolytes affected the surface charge and the stability of HAp suspensions. Proper addition of anionic polyelcctrolyte could lead to finely dispersed HAp suspensions.
