| Abstract | X-ray diffraction (XRD) studies of the phases formed on the surface of the Li-doped PbFe Nb O (PFN) ceramics sintered under different conditions from the mechanically activated mixture of oxides and Li CO have been carried out. At sintering temperatures exceeding 800°C a partial evaporation of PbO leads to the formation of pyrochlore Pb Fe Nb O and lithium ferrites LiFeO and LiFe O phases in the surface layer about 100 m thick. An increase of the Neel temperature by more than 40 K, as compared to single crystal, was achieved in the mechanically activated PFN powder sintered at 600°C. |
