Abstract: | The effects of BaCu(B2O5) (BCB) additions on the sintering temperature and microwave dielectric properties of Li2MgTi3O8 ceramic have been investigated. The pure Li2MgTi3O8 ceramic shows a relative high sintering temperature (∼1000 °C) and good microwave dielectric properties as Q × f of 40,000 GHz, ?r of 27.2, τf of 2.6 ppm/°C. It was found that the addition of a small amount of BCB can effectively lower the sintering temperature of Li2MgTi3O8 ceramics from 1025 to 900 °C and induce no obvious degradation of the microwave dielectric properties. Typically, the 0.5 wt% BCB added Li2MgTi3O8 ceramic sintered at 900 °C for 2 h exhibited good microwave dielectric properties of Q × f = 36,200 GHz (f = 7.31 GHz), ?r = 26 and τf = −2 ppm/°C. Compatibility with Ag electrode indicates this material can be applied to low temperature-cofired ceramics (LTCC) devices. |
