Abstract

Fe_3O_4 Nanocrystallite was synthesized by the hydrothermal method using iron powders and water,and was characterized by means of XRD,FTIR,TEM and TG-DSC.The results show that the Fe_3O_4 obtained at 150℃ for 24h or at 180℃ for 10h consists of nanoplates with an average thickness of about 82 nm or 96 nm,respectively,while that obtained at 180℃ for 24h comprises nanodentries with the diameter in the range of 35-47 nm and 190-714 nm in length.The use of any extra surfactant or template during the synthesis was avoided.The possible formation mechanism of Fe_3O_4 in this hydrothermal system was discussed.
