摘要

A new low-loss, low-temperature sinterable microwave dielectric ceramic Li_2Cu_(0.1)Zn_(0.9)Ti_3O_8 was investigated for the first time. Single phase pure Li_2Cu_(0.1)Zn_(0.9)Ti_3O_8 ceramic with cubic spinel structure was obtained by the conventional solid-state route and sintered at 900 ℃-975 ℃ for 2 h. The ceramic sintered at 950 ℃/2 h exhibits a moderate dielectric constant (ε_r) of 25.2, a high quality factor value (Q×f) of 32 100 GHz. and a near-zero temperature coefficient of the resonant frequency (r_f) of 1.6 ppm/ ℃. The Li_2Cu_(0.1)Zn_(0.9)Ti_3O_8 ceramic can be compatible with Ag electrode, which makes it a promising ceramic for LTCC technology application.
