摘要:
Influence of moderate substitution of Na by monovalent metals Li, K and Ag on structure, phase transitions and dielectric properties of 0.4Na(1/2)Bi(1/2)TiO(3)-0.4SrTiO(3)-0.2PbTiO(3) is studied. Substitution by Li increases, while substitution by K and Ag decreases tetragonality of unit cell. Li increases, Ag decreases while K weakly influences phase transition temperature. The characteristic for the parent phase relaxor state with T-t approaching T-m in case of substitution by K and Li transfers into diffused phase transition without T-m dependence on frequency and extended region of thermal hysteresis.
