This study presents the process of synthesizing BiFeO3 by the Gel – Polymer combustion method under optimal condition, selected through the investigation of influencing factors and the characteristic of materials, including the Gel formation temperature (80°C), the molar ratio of Bi/Fe (1/1), the molar ratio of the mixture metal/PVA (1/3), pH=1, and the sample is heated at 500oC for 2 hours. |
