Аннотация:Bi2VxW1-xO6-y ceramics are synthesized, and their structure and electrical properties are studied. The results indicate that the Bi2WO6-Bi2VO5.5 system contains Bi2WO6- and Bi2VO5.5-based solid solutions in the ranges 0 < x <= 0.2 and 0.75 <= x < 1, respectively. Tungsten stabilizes the high-temperature, tetragonal phase gamma-Bi2VO5.5, which persists down to room temperature at 0.75 <= x <= 0.84. In the range 350-550 degrees C, the electrical conductivity of the bismuth-vanadate-based solid solutions exceeds that of Bi2VO5.5 by about one order of magnitude. The conductivity of the Bi2WO6-based solid solutions is also higher than that of the host phase.
