This paper presents an increase to x = 0.67 of the zirconium content in the conductive Bi2−xZrxO3+δ solid solution. Complete incorporation of Zr in the βIII-Bi2O3 structure, confirmed by X-ray powder diffraction, has produced a phase with a lower volume and superior conductivity than those predicted by an earlier study...
