Preparation and Magnetic Property of Bi2Fe4O9 Nanoparticles by Hydrothermal Method

摘要：

　　Bi2Fe4O9 nanoparticles were prepared at low temperature via a facile,one-step hydrothermal synthesis process using iron(Ⅲ) nitrate nonahydrate (Fe(NO3)3·9H2O) and bismuth nitrate pentahydrate (Bi(NO3)3·5H2O) as starting materials and sodium hydroxide (NaOH) as precipitant and mineralizer.XRD results indicated that the as-prepared nanoparticles are pure orthorhombic Bi2Fe4O9.SEM images revealed that the as-prepared Bi2Fe4O9 nanoparticles have a sheet-like morphology.They are paramagnetic at room temperature demonstrated by the magnetic measurements.
