Co-precipitation Synthesis of BiFeO3 Powders

摘要：

　　Bismuth ferrite powders were synthesized by a simple citric acid complexing co-precipitation method at much lower temperature of 600℃.The work studies the calcination temperature and molar ratio of Fe and Bi on the structure and morphology.The as-prepared BiFeO3 powder was characterized by X-ray diffraction,field emission scanning electron microscopy,transmission electron microscope and Fourier transform infrared spectrophotometer.The result shows that the phase pure BiFeO3 powders with cubic morphology were prepared as the calcination temperature was 600℃ and molar ratio of Fe and Bi was 1∶1.The nanoparticles was uniform with the size of about 200nm.
