Abstract:
The phase analysis of La1-xCaxFeO3-0.5x perovskites prepared by a ceramic process from oxides is studied by X-ray diffraction and differential dissolution methods. At x < 0.5, the system does not form a continuous series of homogeneous solid solutions and does not consist of the members of a homological series. At x < 0.5, the system contains two phases and calcium ferrite nanoparticles located on the surface of lanthanum ferrite. At x > 0.5, the formation of the structures of a brownmillerite-based homological series is found. The catalytic activity of perovskites depends nonmonotonically on the x value and reaches the maximum at x = 0.6.
