Abstract

Bismuth-doped antimonic acids with the empirical formula Sb2O5·xBi2O3·nH2O (0 ≤ x ≤ 0.2) were prepared by reacting an H2O3, aqueous solution with Sb(O-i-C3H7)3and Bi(O-i-C3H7)3. X-ray diffraction confirmed that the anhydrous composites, Sb2O·xBi2O3 (0 ≤ x ≤ 0. 1), are a single cubic Sb2O5phase, where the cubic cell parameter increases linearly from 10.277 to 10.380 Å with the bismuth content x. The electrical conductivity of the polycrystalline disks for Sb2O5·xBi2O3·nH2O (0 ≤ x ≤ 0.1) was evaluated by an ac impedance method at 19.5 °C under various conditions of relative humidity. The conductivity of Sb2O5·xBi2O3·nH2O with x = 0.1 was found to be high (1.0 × 10−3 Scm−1) even at a relative humidity of 68.3%. There was a stronger humidity dependence than that of Sb2O5·xBi2O3·nH2O with x = 0.
