Abstract
Low temperature co-fired ceramics (LTCC) technology is extensively utilized to meet the requirements of device integration and miniaturization. Low-fired Li3Mg2NbO6 ceramics doped with xwt% Li2O–MgO–B2O3–CaF2–SiO2 glass (LMBCS, x = 0.5, 1.0, 1.5, 2.0) were prepared by the solid-state reaction method for applications in microwave communication materials. All samples exhibited a single-phase Li3Mg2NbO6 structure. The addition of LMBCS glass effectively reduced the sintering temperature of Li3Mg2NbO6 ceramics from 1250 °C to 875 °C. And adding LMBCS glass improved the Q × f value of Li3Mg2NbO6 ceramics. The Li3Mg2NbO6-1.0wt% LMBCS ceramics exhibited outstanding microwave dielectric properties: εr = 16.8, Q × f = 89,495 GHz, τf = − 27.4 ppm/°C at 875 °C, which indicates that this ceramic is potential candidate materials for LTCC.
