摘要：

Lead iron niobate, Pb(Fe1/2Nb1/2)O-3 (PFN) ceramics have been produced by sintering PFN powders synthesized from lead oxide (PbO) and iron niobate (FeNbO4), with an effective method developed for minimising the level of PbO loss during sintering. Attention has been focused on relationships between sintering conditions, phase formation, density, microstructural development and dielectric properties. The sintering temperature has been found to have a pronounced effect on the density, grain growth and dielectric properties of the sintered PFN ceramics, with maximum density and relative permittivity values obtained under sintering conditions of 1175 degrees C for 2 h. The origin of the strong dependence of values of epsilon(r) and tan delta on frequency is discussed. (C) 1999 Elsevier Science Limited. All rights reserved.
