“…x O 5.5-3x/2 display an orthorhombic structure for x ≤ 0.1 and a tetragonal γ-phase structure for 0.1 < x ≤ 0.15 [19]. In contrast, Pernot reported that the tetragonal phase was obtained at a dopant concentration of x = 0.07 [20].…”

Solid oxides fuel cells (SOFCs) is one technology that could contribute toward future sustainable energy. One of the most important components of an SOFC is the electrolyte, which must have high ionic conductivity. Cation substitution of vanadium in Bi 4 V 2 O 11 yields a family of fast oxide ion conducting solids known collectively as the BIMEVOXes (bismuth metal vanadium oxide), which have the potential to be applied as electrolytes in SOFCs. The purpose of this work is to study the effect of Ni concentration, when used as a dopant, on the ionic conductivity of Bi 2 Ni x V 1-x O 5.5-3x/2 (BINIVOX) oxides (0.1 ≤ x ≤ 0.2) when prepared by a sol gel method. The gels were calcined at 600 °C for 24 h to produce BINIVOX. These oxides were found to exhibit the γ-phase structure with tetragonal symmetry in space group I4/mmm.

“…The powders formed stabilise in the high temperature ionically conducting tetragonal phase with the Bi 2 VO 5.5 phase formation increasing as a function of ball milling time. 170 For x 0.2 the a phase is present at RT and the g phase, which has the best ionic conductivity, is stable for other compositions. The oxide ion vacancies are in the equatorial plane of the V/Ni co-ordination octahedron.…”

“…The high-temperature #uorite type -Bi O is well known as one of the best anionic conductors due to oxygen vacancies in the structure (4). The discovery that Bi V O was a good oxide ion conductor (5) spawned intensive research on this and related phases (6). An extensive review by Boivin and Mairesse discusses recent developments in fast oxide ion conductors (7).…”
