Abstract

Polycrystalline BaМe_1-xY_xO_3-δ(Me=Co, Fe) samples were synthesized by a conventional route and glycerol–nitrate technique. According XRD patterns of single phase solid solutions BaCo1-xYxO3-δ (0.1≤x≤0.4) and BaFe_0.9-yY_0.1Co_yO_3-δ(0.05≤y≤0.15) were indexed using Pm3m space group. The unit cell parameters were reﬁned using Rietveld full-proﬁle analysis. Oxygen nonstoichiometry of these solid solutions was measured by means of thermogravimetric technique within the temperature range 298–1273 K in air.
