B2O3 was added to Li3NbO4 ceramics to promote the densification process of the ceramics at low temperatures (${\leq} 825$ °C). When the B2O3 content was ${\leq} 0.5$ wt %, a porous microstructure was developed for the specimens sintered at 825 °C. However, when the amount of B2O3 exceeded 0.5 wt %, the Li3NbO4 ceramics were well sintered due to the formation of a liquid phase containing B2O3. The microwave dielectric properties of the Li3NbO4 ceramics were influenced by the amount of B2O3, and the 0.75 wt % B2O3-added Li3NbO4 ceramic sintered at 825 °C for 2 h showed good microwave dielectric properties of $\varepsilon_{\text{r}} = 15.3$, $Q{\times}f = 24600$ GHz, and $\tau_{f} = -45$ ppm/°C. The compatibility between the dielectric and Ag electrode indicated that this ceramic might be a good candidate for microwave low temperature-cofired ceramics (LTCC) devices.
