In_5.5+xSb_1.5-3xW_2xO₁₂ solid solution (0 ≤ x ≤ 0.45) has been synthesized and studied from point of view of structural and electrical properties. The latter exhibits an ordered oxygen-deficient fluorite structure with an ordered cationic distribution. The ρ = f (T) curves corresponding to the the four compositions less rich in W(VI) - x £ 0.20 - shows a resistivity slightly affected by increasing concentration of W(VI). From composition x = 0.25 a significant increase in electrical resistivity was observed, namely one order of magnitude for x = 0.25 compared to x = 0.2 ( ρ_T = 2 x 10^-1 and 2 x 10^-2 Ω.cm, respectively). The presence of antimony, even in low concentration, allows to obtain high levels of electrical conductivity.

Keywords: transparent conductors, solid solution, indium rich oxides, X-ray diffraction, Rietveld refinement, electrical properties.
