Abstract
Ceramics belonging to the Pb5xK6(1−x)Li4(1−x)Ta10O30 solid solution were prepared and characterized by dielectric and a. c. impedance complex measurements. Two types of relaxations were observed: a relaxor behavior and an impedance relaxation.
Characteristics of these two relaxations were studied and explained for a particular composition Pb3.75K1.50LiTa10O30.
