摘要

研究证明了用浇铸法从熔体中合成 Bi12GeO20 时在其结构中用 Si 部分取代 Ge 的可能性。研究了替代对合成多晶材料结构的影响。利用 X 射线相分析和光学显微镜，证实了稳定的硅酸铋和锗酸盐与矽帘石结构形成了一系列连续的固溶体。研究证明，在通过加速冷却（铸造法）从熔体合成 Bi12GeO20 的过程中，Ge 有可能在其结构中被 Si 部分取代。

Synthesis of compounds with a crystal structure of sillenite within the pseudobinary stable system Bi12GeO20–Bi12SiO20*

The possibility of partial replacement of Ge by Si within the structure of Bi₁₂GeO₂₀ during synthesis from a melt by a casting method is demonstrated. The effect of substitution on the structure of synthesized polycrystalline material is studied. Using X‑ray phase analysis and optical microscopy, it is confirmed that stable bismuth silicate and germanate with a sillenite structure form a continuous series of solid solutions. The possibility of partial replacement of Ge by Si within the structure of Bi₁₂GeO₂₀ during its synthesis from a melt by accelerated cooling (casting method) is demonstrated.
