Abstract

The two silver vanadium oxide phases-Ag₂V₄O ₁₁ and Ag₄V₂O₆F₂-were prepared by hydrothermal synthesis. The electrical conductivity of both silver vanadate powders was determined by the powder-solution-composite (PSC) method. The conductivities obtained were 0.0085∈±∈0.0005 and 0.0005∈±∈0.00015 S/cm for the Ag₂V₄O ₁₁ and Ag₄V₂O₆F₂, respectively, the first such report for the Ag₄V₂O ₆F₂ phase. The optical gap and the transmission where studied by diffuse reflectance. Both were larger for Ag₄V ₂O₆F₂ than Ag₂V₄O ₁₁, concomitant with a decrease in carrier content.
