Abstract

Fine particle strontium substituted lanthanum ferrites La1-xSrxFeO3, where x = 0.0-1.0, have been synthesized by the solution combustion method using corresponding metal nitrates, oxalyl dihydrazide (ODH) or tetra formal tris azine (TFTA). Formation of La1-xSrxFeO3 was confirmed by the XRD and the fine particle nature of the ferrites investigated using SEM, particle size analysis and BET surface area measurements. La1-xSrxFeO3 (up to x = 0-0.4) exhibited low resistivity near the Neel temperatures. La1-xSrxFeO3 with x greater than or equal to 0.8 when used as bifunctional electrodes, showed oxygen evolution and reduction activity comparable with the orthoferrites prepared by the conventional solid state method.
