本文报告了通过溶胶-凝胶法制备 CaO-P2O5-SiO2 凝胶并进行系统分析的结果。 SiO2 浓度对这些凝胶的影响，发现结果非常令人鼓舞。研究表明，SiO2 的浓度对这些凝胶的相形成影响很小。它在较低的浓度值下具有明显的变化，从结构较少的颗粒到在较高浓度的 SiO2 下最终生长为高度结晶的纤维性质。作者通过扫描电子显微镜和能量色散分析仪（SEM/EDS 技术）以及傅里叶变换红外光谱 (FTIR) 和 X 射线衍射 (XRD) 光谱数据检查了这些凝胶形态的变化，并报道了含有纤维状 β-Ca(PO3)2 作为所研究材料中主要相的结晶产物。
This paper reports on the results concerning the preparation and systematic analysis of CaO–P2O5–SiO2gels by a sol–gel process. The concentration of SiO2influence on these gels and found the results are very encouraging. Studies have revealed that the concentration of SiO2has a marginal influence on the phase formation of these gels. It has appreciable changes from less configured particles at lower values of concentration, with an ultimate growth in a highly crystalline fibrous nature at higher concentrations of SiO2. The authors have examined the changes in the morphology of these gels by a scanning electron microscope with an energy dispersive analyser (SEM/EDS techniques) and also from the profiles of Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD) spectral data and reported the crystalline product containing the fibrous β-Ca(PO3)2as a major phase in the materials studied.
