Abstract

In the preparation of ceramic SrCe0.95Yb0.05O3−α great care was taken to obtain a homogeneous, carbonate free and dense material of exactly the given composition. The material is an important high-temperature protonic conductor (HTPC). X-ray powder diffraction data are reported. The cell parameters obtained are a=6.007(2) Å, b=12.296(3) Å, c=8.588(2) Å, cell volume 634.4(1) Å3, Z=8. The space group is most probably Pnma (62) and Dx=5.806(2) g/cm3. The bending strength of the sintered dense material is 175±6 MPa.
