摘要：

Li3Mg2NbO6 + xwt% Li2O-MgO-ZnO-B2O3-SiO2(LMZBS,x = 2, 4, 6, 8, 10) microwave dielectric ceramics with the rock-salt structure were primarily investigated by the traditional solid-state method. The microstructures, microwave dielectric properties, and sintering characteristics were studied systematically according to the doping concentration and sintering temperature. It could be seen that the LMZBS glass effectively lower the sintering temperature of Li(3)Mg(2)NbO(6)ceramics from 1250 to 925 degrees C with microwave dielectric properties changing as a function of the amounts of the LMZBS glass. The experimental results showed that 4 wt% LMZBS glass enabled Li(3)Mg(2)NbO(6)ceramics sintered at 925 degrees C for 4 h to have excellent microwave dielectric properties:epsilon(r) = 16.02,Q x f = 56,455 GHz,tau(f) = - 18.81 ppm/degrees C. Therefore, Li(3)Mg(2)NbO(6)ceramics doped with LMZBS glass meet the requirements of low-temperature co-fired ceramics.
