Abstract
BiFeO3 fine particles were prepared by hydrothermal reaction using Bi(NO3)3•5H2O and Fe(NO3)3•9H2O as starting materials in KOH solution. The X-ray powder diffraction pattern of the product synthesized under the condition of K/Bi molar ratio of 160 at 180ºC showed a single phase of the perovkite-type BiFeO3. The lattice parameters of that powder sample were a=5.5844(9) and c=13.867(1)A with the hexagonal cell, and these values agreed well with the published ones (a=5.57874(16) and c=13.8688(3)A).
