Title: | Synthesis of bismuth ferrite nanoparticles via a wet chemical route at low temperature | Authors: | Hu, Y Fei, L Zhang, Y Yuan, J Wang, Y Gu, H |
Issue Date: | 2011 | Source: | Journal of nanomaterials, 2011, v. 2011, 797639, p. 1-6 | Abstract: | Nanoparticles (NPs) of multiferroic bismuth ferrite (BiFeO₃) with narrow size distributions were synthesized via a wet chemical route using bismuth nitrate and iron nitrate as starting materials and excess tartaric acid and citric acid as chelating agent, respectively, followed by thermal treatment. It was found that BiFeO₃NPs crystallized at ∼350℃ when using citric acid as chelating agent. Such crystallization temperature is much lower than that of conventional chemical process in which other types of chelating agent are used. BiFeO₃ NPs with different sizes distributions show obvious ferromagnetic properties, and the magnetization is increased with reducing the particle size. | Keywords: | Bismuth ferrite nanoparticles Bismuth ferrites Bismuth nitrates Chelating agent Chemical process Crystallization temperature Different sizes Ferromagnetic properties Iron nitrates Low temperatures Multiferroics Narrow size distributions Starting materials Tartaric acids Thermal treatment Wet chemical route Bismuth Citric acid Ferrite Nanoparticles Chelation |
