摘要：

Li4Ti5O12 ceramics with different amount of MoO2 addition were densified at 850 degrees C via a solid-state reaction route. Pure phases and dense crystal morphology were obtained. Our experimental results indicated that the tau(f) value of the Li4Ti5O12 ceramic can be adjusted to near zero via adopting suitable amount of MoO2 addition. Among all the modified Li4Ti5O12 specimens, the sample with 4 wt.% of MoO2 addition (marked as LM4 in this paper) possessed good microwave dielectric properties: epsilon(r) = 20.76, Q x f = 18308 GHz (7.99 GHz), tau(f) = (-02.96 ppm/degrees C. It is suggested that the MoO2 modified Li4Ti5O12 ceramics are suitable candidates for LTCC applications in microwave devices.
