Abstract
Li3Mg2NbO6 ceramics modified with Li2O–B2O3–SiO2–CaO–Al2O3 (LBSCA) glass additives were densified below 950 °C via a solid-state route. Single orthorhombic phase and dense morphology were obtained with the LBSCA glass introduction. Promising microwave dielectric properties, especially with an improved Q × f value, were obtained in the Li3Mg2NbO6 ceramics with 0.5 wt% of the LBSCA glass addition sintered at 925 °C for 4 h: er = 15.16, Q × f = 90,557 GHz, τf = − 16.22 ppm/°C. It is suggested that the microwave dielectric performance was highly related to the densification, the polarizability, and the effects of the packing fraction. All experimental facts indicate that the LBSCA modified Li3Mg2NbO6 ceramics are potential candidates for Low-Temperature Co-fired Ceramic (LTCC) applications.
