摘要:
The compositions are derived from Bi4V2O11 and are characterised by the fact that at least one of the elements present is substituted, the substituting element(s) being such that the structural nature of the gamma phase of Bi4V2O11 is maintained, as well as the equilibrium of the loads.

Les compositions de l'invention sont dérivées de Bi4V2O11 et sont caractérisées en ce que l'un au moins des éléments constitutifs est substitué, le ou les élément(s) substituant(s) étant tel(s) que le type structural de la phase gamma de Bi4V2O11 est maintenu ainsi que l'équilibre des charges.
摘要:
Composite structure comprising an electrolyte and electrodes, in particular for oxygen pumps. Said structure includes a solid, essntially gas tight O2 anion conductor electrolyte, said electrolyte being in contact with two electrodes, a gas-porous cathode and anode, at least the cathode or the anode being a volume electrode comprising (i) at least one BIMEVOX type compound (ii) an electronic conductor forming a distinct solid phase, dispersed in the BIMEVOX type compound so as to define respective volumes of said volume electrode, a plurality of triple contact points between an ambient gaseous atmosphere, the electrolyte and the electronic conductor.
