Dielectric properties of [Ca1-x(Li1/2Nd1/2)x]1-yZnyTiO3 ceramics at microwave frequencies

Description

Dielectric properties of Ca1-x(Li1/2Nd1/2)xTiO3 (0.0≤x≤0.6, CLNT) and [Ca0.6(Li1/2Nd1/2)0.4]1-yZnyTiO3 (0.5≤y≤1.0, CLNZT) ceramics were investigated at 4-10 GHz. For the CLNT system, a single perovskite phase was detected in the entire composition range. The dielectric constants (K), and the temperature coefficients of the resonant frequency (TCF) were dependent on the B-site bond valence. Qf value decreases with the increase in (Li1/2Nd1/2)TiO3 content (x) due to a decrease in grain size. For the CLNZT system, Qf value and TCF were improved with Zn content (y) due to the formation of Zn2TiO4. Typically, K of 47, Qf of 13000 GHz, TCF of 14 ppm per deg. C were obtained for [Ca0.6(Li1/2Nd1/2)0.4]0.4Zn0.6TiO3 sintered at 1150 deg. C for 4 h
