Inorganic Materials Aims and scope

Abstract

We have determined the extent of La1 − x Ba x Mn1 − y Fe y O3 solid solutions with orthorhombically and rhombohedrally distorted perovskite structures. A partial phase diagram of the LaMnO3 + δ-BaMnO3-BaFeO2.5-LaFeO3 system in air at a temperature of 1373 K has been proposed for the first time. We have measured the relative length change of La1 − x Ba x Mn1 − y Fe y O3 samples and calculated their thermal expansion coefficients.
