Abstract

Bismuth ferrite (BiFeO₃) nanopowders were synthesized by a sol-gel method at the temperature as low as 450 °C. The obtained sol was transparent and homogenous when the mixture ionic concentration was properly controlled with the help of ethylene alcohol. The preparation process of crystalline BiFeO₃ could be divided into three stages: (i) the evaporation of organics and decomposition of nitrogen-containing organics below 200 °C; (ii) the collapse of Bi-Fe gel network in the temperature range of 200-300 °C and (iii) the formation of BiFeO₃ nanopowders by the solid-state reaction between Bi₂CO₃O₂ and Fe₂O₃.
