“…[13] was followed to obtain the real impedance of the samples. Figure 1(a) shows the diffraction pattern of specimens calcined at 650 ℃ in which impurity peak (shown by *) of BiVO 4 (secondary phase) [17] has been observed for all compositions which has gradually become prominent with an increase in dopant concentration. The X-ray diffractograms of specimens after calcination at 750 ℃ and sintering at 800 ℃ are shown in Figs.…”

“…This high ionic conductivity in the intermediate temperature range compared to other fluorite and perovskite-type electrolytes make BIMEVOXes as potential electrolytes viable for low temperature operation. Furthermore, in order to obtain improved ionic conducting properties, BIMEVOX group has also been explored as a different system, i.e., BIMEME*VOX [13][14][15][16][17] by double substitution at both Bi/V and/or only V-sites.…”

“…One of the oxide materials that had high oxide ion conductivity and the potential application was Bi2V1-xMexO5.5-σ (BIMEVOX), where ME was dopant [1][2][3]. Dopant at a certain concentration plays an important role in improving the ease of oxygen ions migration of Bi2VO5.5 [4][5]. Therefore, in addition to the migration path of oxygen ions, the search for a type of dopant with a certain concentration was needed to obtain BIMEVOX with high conductivity.…”
