Preparation and Characterization of Sr(RE_(1/2)Nb_(1/2))O_3 [RE=La, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Y, Yb, Ga] Microwave Dielectric Ceramics

摘要

Microwave dielectric ceramics based on Sr(RE_(1/2)Nb_(1/2))O_3 (RE=La, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Y, Yb, Ga) have been prepared by the solid state ceramic route. The samples are characterized by XRD, SEM and microwave methods. The ceramics have high dielectric constants in the range of 22-30, low dielectric losses and a small temperature variation of the resonant frequency.
