Abstract
Ceramics belonging to the Pb5xK6(1-x)Li4(1-x)Ta10O30 Solid solution were pr epared and characterized by dielectric and a. c. impedance complex measurem ents. Two types of relaxations were observed : a relaxer behavior and an im pedance relaxation. Characteristics of these two relaxations were studied and explained for a p articular composition Pb3.75K1.50LiTa10O30.
