| Abstract: | BiFeO3 powder has been synthesized by the hydrothermal method,using bismuth nitrate Bi(NO3)3·5H2O] and iron nitrate Fe(NO3)3·9H2O] as raw materials,potassium hydroxide(KOH) as mineralizer,polyethylene glycol(HO(CH2CH2O)nH)6000 as dispersant,the samples were characterized by XRD,Raman spectra,the experiment results show that BiFeO3 powder obtained at 200 ℃ for 6 h is pure single phase.Thermal analysis results obtained the neel temperature and the curie temperature of BiFeO3 powder. |
