Zinc- (Zn) doped hydroxyapatite (HAp) were prepared by sol-gel method. Zinc-doped hydroxyapatite (ZnHAp) and HAp were analyzed by X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS). The Rietveld analysis revealed that the HAp and 7ZnHAp powders obtained by sol-gel method have a monophasic hydroxyapatite structure belonging to the P6 spatial group. The results obtained from the ultrasound characterization of HAp and ZnHAp are also presented in this study. The effect of zinc concentration on properties that were deduced from ultrasonic measurements are studied in the case of a significant zinc concentration (x = 0.07). From the values of the ultrasonic waves velocities were determined by the pairs of elastic coefficients of the suspensions (Young modulus E, Poisson coefficient ν), which have proven to be similar to those determined by other authors.
采用溶胶-凝胶法制备了锌掺杂羟基磷灰石（HAp）。通过 X 射线衍射（XRD）和 X 射线光电子能谱（XPS）对锌掺杂羟基磷灰石（ZnHAp）和 HAp 进行了分析。Rietveld 分析表明，溶胶-凝胶法得到的 HAp 和 7ZnHAp 粉末具有单相羟基磷灰石结构，属于 P6 空间群。本研究还介绍了 HAp 和 ZnHAp 的超声特性研究结果。在锌浓度较大（x = 0.07）的情况下，研究了锌浓度对超声测量推断性能的影响。根据悬浮液的弹性系数（杨氏模量 E、泊松比 ν）对超声波速度的测定值，这些值与其他作者的测定值相似。
