样品在 r-SBF 溶液中暴露不同时间后的 GIXRD 图如图 9 所示。除了对应于 Zn 相的主要峰外,还有一些强度较低的峰 Zn3(PO4)2、Ca3(PO4)2和CaHPO4·2H2O在浸泡168小时后在样品上检测到。没有 ZnO 或 Zn(OH)2 的峰,这可能是由于它们的含量低,无法通过 XRD 检测到。
The GIXRD patterns of the samples after exposure to r-SBF solution for different time are displayed in Fig. 9. In addition to the dominant peaks corresponding to the Zn phase, a number of peaks with low intensity for Zn3(PO4)2, Ca3(PO4)2 and CaHPO4·2H2O were detected on the samples after immersion for 168 h. Peaks of ZnO or Zn(OH)2 were absent, possibly attributed to their low contents, which cannot be detected by XRD.
