This study explores the possibility of obtaining solid solutions with the composition CaBiNa(PO)(VO)O (0 < x ≤ 6) and investigating their physicochemical and medicobiological properties. Using solid-state synthesis method, only the composition CaBiNa(PO)(VO)O was obtained, while for other values of x, mixtures of apatite and secondary phases or mixtures of various vanadates and phosphates without the target apatite structure were obtained. The study considers the dimensional crystal chemical factors influencing the possibility of forming solid solutions in a wide range of compositions. The crystal structure of CaBiNa(PO)(VO)O was refined by the Rietveld method ( = 9.45154(37) Å, = 6.93659(28) Å, = 536.638(47) Å, R-Bragg = 3.718 %) and confirmed by group analysis of the IR spectrum. Standard MTT test showed that this substance is not cytotoxic at dilutions of 1:2 and higher. No bactericidal activity against and cultures was observed.

钒对钙铋钠氧磷灰石结构和性能的影响

本研究探讨了获得具有 CaBiNa(PO)(VO)O (0 < x ≤ 6) 成分的固溶体的可能性，并研究了其物理化学和医学生物学特性。采用固相合成方法，仅得到组成CaBiNa(PO)(VO)O，而对于其他x值，则得到磷灰石和第二相的混合物或各种钒酸盐和磷酸盐的混合物，而没有目标磷灰石结构。该研究考虑了影响多种成分形成固溶体可能性的维晶体化学因素。 CaBiNa(PO)(VO)O 的晶体结构通过 Rietveld 方法精修 ( = 9.45154(37) Å, = 6.93659(28) Å, = 536.638(47) Å, R-Bragg = 3.718 %) 并通过红外光谱的群体分析。标准 MTT 测试表明，该物质在 1:2 及更高稀释度下不具有细胞毒性。没有观察到针对 和 培养物的杀菌活性。
