Synthesis of Bismuth Ferrite and La –doped Bismuth ferrite by auto combustion technique

Abstract

BiFeO3 is a multiferroic compound which has varied application in sensors and actuator. It shows both ferroelectric and antiferromagnetic property. In the present work BiFeO3 and La-doped BiFeO3 were synthesized by auto combustion technique using glycine as fuel. Glycine to nitrate ratio was kept at 0.1. Phase pure powder can be prepared at 500oC. Synthesized powder was characterized by X-ray diffraction. DSC-TG was used to find out the thermal behavior of synthesized gel and agglomeration tendency and morphology of powder were studied by SEM. La substitution greatly modified the structure of BiFeO3.
