| Abstract |
| Lead Iron Niobate (PFN) powder, prepared by semi-wet-hydroxide
route, was doped with different concentrations of Mn20 3. The
powders were compacted into pellets and these were then
sintered at 1 ooocc in PbO atmosphere. The dielectric constant
and loss tangent of these ceramics were measured in the temperature
range, 25°·130°C. The effects of different concentrations
of Mn203 doping on the microstructure, dielectric constant, loss
tangent and Curie temperature of PFN are reported in this study. |
