Abstract: In the work the Pb(Fe1/2Nb1/2)O3 ceramics was obtained by a two-stage synthesizing method (columbite method). During the technological process the synthesis took place as a result of powder calcination method. An influence of technological conditions of the first stage of the ferroniobate (FeNbO4) synthesizing on the crystalline structure, the microstructure, the internal friction and relative density (_eksp/_teor) was presented, and they influence basic properties of (e(T) and tand(T), Tm, S(E), P(E)) and electric conduction of the PFN ceramics. It has been found that a high temperature of the FeNbO4 synthesizing does not improve properties of the material and the optimum parameters of the PFN ceramics are obtained while synthesizing of FeNbO4 at the temperature of 1000C for 4 h.
