摘要/Abstract

摘要： 选用聚乙二醇2000、六偏磷酸钠和BK Giulini公司提供的粉体分散剂LoponR 885对化学沉淀法制备的HA进行水中分散性试验研究. 用粒度分布仪、X射线衍射仪（XRD）和透射电子显微镜（TEM）对分散体系进行粒度分布、形貌和物相分析. 对粉末HA颗粒的团聚及分散机理进行了探讨. 结果表明，采用这种方法得到的粉体的组成相以羟基磷灰石（HA）为主,且颗粒具有近似球形的微观形貌. (NaPO3)6和LoponR 885对HA颗粒团聚的消弱作用明显. 可以认为合理选用分散剂是在不影响HA粉体品质前提下消除HA颗粒团聚现象的有效方法.

Abstract: HA particles were synthesized by the chemical precipitation method and dispersed by the solutions of PEG 2000, (NaPO3)6 and LoponR 885 in water. The effect of different dispersants in the process on prepared HA powder was analyzed. This paper analyzes the dispersed HA by the means of XRD, TEM and particle size analyzer. The results indicate that a majority of constitution of the powders is mainly HA, and the HA particles dispersed by (NaPO3)6 and Lonpon885 become smaller, and the particles take approximately spherical shape. So, the proper selection of dispersant is an effective method to prepare highly dispersed HA powders.
