Preparation and Characterization of Nano Bi2Sn2O7 via Water/Oil Microemulsion
Abstract:
The precursor of bismuth stannate(Bi2Sn2O7) was prepared by precipitation reaction in the nanodroplets of water/TX100/n-hexanol/cyclohexane microemulsion system.Some factors that affected the size and shape of the precursor were investigated.Spherical bismuth stannate particles with single pyrochlore structure were obtained when the precursor was calcined at a temperature as low as 500℃.The particle size was in the range of 10~20 nm with a mean size close to 10 nm.The IR bands were broadened when calcined at 500℃.
