摘要：

New ferrielectric 0.9Ag(0.9)Li(0.1)NbO(3)-0.1Bi(0.5)K(0.5)TiO(3) ceramics have been obtained. At room temperature ceramics exhibit perovskite structure, which is close to rombohedral-tetragonal phase boundary. The dielectric properties of ceramics were investigated in wide frequency range from 20Hz to 1GHz at temperatures 200K-750 K. 0.9Ag(0.9)Li(0.1)NbO(3)-0.1Bi(0.5)K(0.5)TiO(3) ceramics exhibits a first order mixed order-disorder and displacive ferroelectric phase transition at T-C = 430K. The phase transition dynamics is caused by relaxation soft mode at frequencies below 1GHz and soft phonon mode at higher frequencies. In ferroelectric phase an additional dielectric dispersion is observed, which could be attributed to dipolar glass relaxation.
