Abstract: An aim of this work was to determine an influence of an admixture, the chromium (for x from 0.01 to 0.06), on the mechanical properties of the PFN ceramics. The ceramics with chemical composition Pb(Fe0.5-xCrxNb0.5)O3was synthesized in two steps from simple oxides PbO, Fe2O3, Nb2O5, Cr2O3. The first stage was based on obtaining the FeNbO4from the Fe2O3 and Nb2O5simple oxides. At this stage an admixture in a form the Cr2O3chromium oxide was added to the solution. In the second stage the PbO lead oxide and the doped FeNbO4(obtained earlier) were synthetized. The sintering of ceramic samples PFCN type was carried out by free sintering method. Temperature measurements of the internal friction were conducted on a computer-controlled automatic resonant mechanical spectrometer (heating cycle with 3 deg/min).
