The PbFe_{1/2}Nb_{1/2}O_3 (PFN) ceramics can be obtained by a lot of ways. There are a lot of methods and techniques to synthesize the PFN powder such as: reactions in the solid phase by one-stage or two-stage synthesizing method (the columbite method), molten salt synthesis, sol-gel, co-precipitation method and sintering of compacts from a loose mixture of powders. Each of them requires accuracy and precision to conduct a technological process, aiming at obtaining a product with the optimum parameters. In the work PFN specimens were obtained by one-stage synthesis methods using two different powder synthesizing techniques: by calcining (sintering of a loose mixture of the PFN powder) and as a result of sintering of pressed compacts from the PFN powder mixture at high temperature (pressing). The obtained specimens were subjected to X-ray and micro-structural examinations and tests of internal friction and dielectric properties. The tests showed that the ceramics obtained by the powder calcining method has better applied properties.

In this work an attempt was made to obtain three compositions of the solid solution (1-x)Pb(Fe_{0.5}Nb_{0.5})O_{3}-(x)BiFeO_{3} for x=0.8, 0.7 and 0.6. The obtained specimens were subjected to microstructure and dielectric examinations and temperature dependences of the internal friction Q^{-1}(T) and Young's modulus E(T).
