| 中文摘要: |
| 以十六烷基三甲基溴化铵(CTAB) 和聚乙二醇(PEG) 为分散剂,采用包覆沉淀法制备纳米羟基磷灰石(HA)胶体,经干燥和烧结后获得HA 粉体,并利用X 射线衍射仪、透射电子显微镜考察了所得粉体的物相和形貌。结果表明,CTAB 或PEG 的添加量均对羟基磷灰石颗粒的形状和粒径有影响,控制合适的添加量可以使粒径变小,长径比增大。 |
| 英文摘要: |
| Nano-hydroxyapatite colloid was prepared by the method of precipitation. The CTAB and PEG were added to encapsulate the colloid, that was dried and sintered. The phase composition and morphology of the powder were characterized using X-ray diffraction and TEM . The results show that the adding of CTAB and PEG can disperse HA, the size is reduced and aspect ratio is increased. |
