Kopsavilkums

Influence of moderate substitution of Na by monovalent metals Li, Kand Ag on structure, phase transitions and dielectric properties of 0.4Na _1/2Bi_1/2Ti O₃-0.4SrTiO₃-0. 2PbTiO₃ 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 Kand Li transfers into diffused phase transition without T_m dependence on frequency and extended region of thermal hysteresis.
