以Na3PO4·12H2O,Ca(NO3)2·4H2O为前驱体,通过调节pH值控制PO43-的生成,利用微波液相法合成针状纳米羟基磷灰石(n-HA),采用X射线衍射(XRD)仪、拉曼光谱(RS)、红外光谱(FT-IR)、透射电镜(TEM)等对粉体相组成和形貌进行分析。结果表明,微波液相法可以快速合成类骨n-HA晶体,合成的n-HA晶体呈针状,尺寸在(10~20)nm×(50~70)nm之间,随着微波加热时间的延长,n-HA晶体的结晶程度升高,晶体形貌从针状向短柱状转变。
The precursor of Na3PO4 · 12H2O and Ca (NO3) 2.4H2O was used to control the formation of PO43- by adjusting the pH. The acicular nano-hydroxyapatite (n-HA) was synthesized by microwave liquid phase method and characterized by X-ray diffraction XRD, Raman spectroscopy (RS), infrared spectroscopy (FT-IR) and transmission electron microscopy (TEM). The results show that the microwave-assisted liquid phase method can rapidly synthesize n-HA crystal, the synthesized n-HA crystal is acicular with the size of (10-20) nm × (50-70) nm. With the microwave heating time , The degree of crystallization of n-HA crystals increased, and the morphology of the crystals changed from acicular to short column.
