Abstract

The effects of B2O3–LiF addition on the phase composition, microstructures, and microwave dielectric properties of (Mg0.95Cu0.05)2SiO4 ceramics fabricated by a wet chemical method were studied in detail. The B2O3–LiF was selected as liquid-phase sintering aids to reduce the densification sintering temperature of (Mg0.95Cu0.05)2SiO4 ceramics. The B2O3 6%–Li2O 6%-modified (Mg0.95Cu0.05)2SiO4 ceramics sintered at 1200°C possess good performance of εr ∼ 4.37, Q×f ∼ 36,700 GHz and τf ∼ −42 ppm/°C.
