New silicon substituted BiMeVO(x): synthesis and study of structural properties in relation to ionic conductivity

Partial substitution of vanadium with silicon in the compound Bi(4)V(2)O(11), which belongs to the Aurivillius family, leads to the creation of a solid solution Bi(4)V(2−x)Si(x)O(11−δ) (0 ≤ x ≤ 0.4). The compound with x = 0.1 turns out to be a monoclinic α-form of Bi(4)V(2)O(11), while the compounds...

description Partial substitution of vanadium with silicon in the compound Bi(4)V(2)O(11), which belongs to the Aurivillius family, leads to the creation of a solid solution Bi(4)V(2−x)Si(x)O(11−δ) (0 ≤ x ≤ 0.4). The compound with x = 0.1 turns out to be a monoclinic α-form of Bi(4)V(2)O(11), while the compounds with x = 0.2 and x = 0.3 are orthorhombic β-polymorphs, and the compound with x = 0.35 is of tetrahedral γ-polymorph. Electrochemical Impedance Spectroscopy has been used to measure the ionic conductivity of doped samples. The ceramic sample with x = 0.1 has the highest ionic conductivity values.
