The XRD diffraction patterns of (La0.3Sr0.6Ce0.1)0.9Me0.1Ti0.9O3-δ (Me= Co, Cu, Fe, Mn, Ni) materials after reduction at 1100 deg.C in hydrogen

The (La0.3Sr0.6Ce0.1)0.9Me0.1Ti0.9O3-δ (Me= Co, Cu, Fe, Mn, Ni) materials were synthesized via the solid state reaction method and examined as a potential anode material. First, the mixed oxide reagents were pressed into pellets and calcined at 1200 °C for 12 hours to decompose most of the organic compounds. The resulting calcined pellet was ground in an agate mortar, pressed back into pellets, heated in an oven at 1400 °C for 12 hours and cooled to room temperature at a rate of 5 °C/min. The XRD analysis allowed for determining the phase composition of powders after reduction at 1100 deg.C in hydrogen.
