摘要
以硝酸钙和磷酸二氢铵为原料用共沉淀法制备纳米羟基磷灰石(HA),采用X射线衍射、透射电子显微镜、热重 差示扫描量热等手段对样品形态结构进行表征.结果表明,制备的六方晶型纳米羟基磷灰石长轴约为60nm,短轴约为20nm,粒径均匀且分散性较好.该文还研究了纳米HA对Ag+的吸附性能.
Nanosized hydroxyapatite particles were prepared by the coprecipitation of Ca(NO_3)_2 and (NH_4)H_2PO_4. The prepared particles were characterized with X-ray diffractometry (XRD), transmi-(ssion) electron microscopy (TEM) and thermal gravimetry-differential scanning calorimetry ((TG/DSC).) The results show that homogenous particles with good dispersion are hexahedron (hydro)-(xyapatite). The average major axial diameter of the particle size is about (60 nm) and the average minor axial diameter is about (20 nm). Several parameters are taken into account in the adsorption of Ag^+ ions into them.
