本实验通过双掺杂氧化镝和氧化钨于氧化铋与单掺杂氧化铒于氧化铋所制成的两种电解质进行对比。利用粉末 X射线衍射对合成材料进行相分析，利用交流阻抗谱方法测试、计算试样的电导率。研究结果表明，烧结温度选取在800℃时， ESB电解质的结晶度要比 DWSB 电解质的结晶度要好，并且双掺杂 DWSB 电解质的晶格常数明显比单掺杂 ESB 电解质的晶格常数要大。与单掺杂的 ESB、 DSB、 WSB 电解质相比，双掺杂的 DWSB 电解质其结构与δ-Bi2 O3的内在结构更加的相近，致使双掺杂的电解质要比单掺杂的电解质的电导率要高。

Through compared the Bi2 O3 -double doped Dy2 O3 and WO3 electrolyte with Bi2 O3 -single doped ErO3 electrolyte. Phase distribution in synthesized samples was analyzed by X-ray diffraction technique, and conductivities of the samples were measured and calculated by using an AC impedance analyzer. The results showed that the crystallization of ESB electrolyte was better than the crystallization of DWSB electrolyte when the sintering temperature was at 800 ℃, and the lattice constant of double doped DWSB electrolyte was significantly larger than the lattice constant of single doped ESB electrolyte. Compared with the single doped ESB, DSB, WSB electrolyte, the structure of double doped DWSB electrolytes were more similar with the internal structure of δ-Bi2 O3 , so the conductivity of double doped electrolyte was higher than the single doped electrolyte.
