Description

La0.75Sr0.25Mn0.5Cr0.2Ti0.3O3 has been synthesized in solid state reaction method and tested as a potential anode material for solid oxide fuel cells. Rietveld refinement of X-ray powder diffraction data of the composition using Fullprof software shows that the materials crystallize in the rhombohedral symmetry in the R-3C space group. The cell parameters are: a = b = 5.5143 (4) Å, c = 13.452(1) Å, α = β = 90°, δ = 120°. Addition of titanium to the B-site of La0.75Sr0.25Mn0.5Cr0.2Ti0.3O3-δ yields a total conductivity of 1.96 Scm-1 in air at 800 °C with activation energy of 1.02 eV. (paper)
