摘要：
A new high-Q, low-temperature microwave dielectric ceramic with composition Li2Cu0.2Mg0.8Ti3O8 and a cubic spinel structure was prepared at 900-975 degrees C for 2 h by the conventional solid-state route. The ceramic sintered at 950 degrees C for 2 h exhibits optimum dielectric properties with a moderate dielectric constant of 28.1, a high quality factor of 34,300 GHz and a near-zero temperature coefficient of resonance frequency of 9.4 ppm/degrees C. The Li2Cu0.2Mg0.8Ti3O8 ceramic can be compatible with Ag electrode, which makes it a promising ceramic for LTCC technology application. (C) 2013 Elsevier Ltd and Techna Group S.r.l.
