Abstract
Structural and dielectric properties of Potassium Lithium Niobate polycrystalline ceramic K3Li2Nb5O15 (KLN), having the tetragonal tungsten bronze (TTB) – type structure are studied in the temperature interval 50−550 °C. Special emphasis is given to the diffuse phase transition occurring around 440 °C. Space charge polarization, relaxation phenomena and free charge conductivity have been elucidated using impedance spectroscopy technique. Argand plots have revealed a non Debye and polydispersive type relaxation. In paraelectric phase the Arrhenius activation energy E τ = 0.533 eV was determined. The structural and dielectric results are compared with two others TTB compounds derived from KLN family: Pb1.85K1.15Li0.15Nb5O15 (PKLN) and GdK2Nb5O15 (GKN).
