Abstract: | In this work we report the synthesis of the Pb(Fe0.5Nb0.5)O3 (PFN) powders and sintered ceramics. The ceramics were prepared from oxides: Fe2O3, Nb2O5 and PbO by two-stage columbite method by calcination. PFN powders were dried and formed in samples in shape of discs (10 × 1) mm3 and rectangular bars (26 × 10 × 1) mm3. The samples were sintered by conventional ceramic sintering (CCS) method at temperature of 1323 K for 2 h in air. The density of the ceramic samples was determined to be ρ = 8200 kg/m3. The obtained results of investigations of electric and mechanical properties such as: Young’s modulus E, electric permittivity ε and tangent of dielectric loss of angle tan δ of the Pb(Fe0.5Nb0.5)O3 ceramics obtained are presented. |
