“…The heating rate was maintained at 1 • C/min in both heating and cooling runs. as reported so far [12]. An additional band is observed at nearly 444 cm −1 properly assigned to stretching mode of Bi-O bond vibrations [13,14] in bismuthate layers.…”

“…4. It is clearly noted that the parent compound (x ¼ 0.0) exhibits the IR spectrum of a-Bi 4 V 2 O 11 as reported in literature [28]. The bands observed in frequency range from 527 to 990 cm À1 are associated with the vibration of VO 4 tetrahedra.…”

“…Major characteristic lines for some compositions are given in Table 2 (Table 2). These results correspond to those in the paper [20] indicating mainly tetrahedral coordination of vanadium atoms surrounded by oxygen atoms. Bands in the low-frequency region 70-200 cm −1 according to the paper [21] also correspond to the oscillations of the bismuth-oxygen Bi 2 O 2 layer.…”

Solid solutions Bi 4 V 2-x Fe x/2 Nb x/2 O 11-δ (х=0.05-1.0) and Bi 4 V 2-х-y Fe x Nb y O 11-δ (with fixed x or y=0.2 and variable х or y=0.2-0.5 with step 0.1) were synthesized by the standard ceramic technology in the temperature range 773-1113 K and by mechanochemical activation method using Bi 2 O 3 , V 2 O 5 Fe 2 O 3 , and Nb 2 O 5 oxides as initial compounds. The formation of solid solutions was studied. Ranges of stability and temperature values of phase transitions for different polymorphous modifications were defined using dylatometric and thermo gravimetric studies. The morphology and the local chemical composition of the ceramic samples were studied. Samples with concentration of dopants x>0.3 contain two phases; both major and impurity phases are solid solutions of the BIFENBVOX type although the dopants atoms distribution between them is random. The thermal expansion coefficients (TEC) were measured. The electrical conductivity of ceramic samples was investigated in a wide range of temperatures. The highest conductivity values among the studied solid solutions are observed for the sample with a small amount of dopants x=0.25.
