N2 - Ultra-low-firing-temperature ceramics (Mn1−xMgx)V2O6 (x = 0–1) were prepared using the conventional solid-state reaction method. The effects of the Mn:Mg ratio on the crystal structure and microwave dielectric properties of the prepared ceramics were systematically investigated. The results indicated that an appropriate Mn:Mg ratio effectively improves the dielectric properties of the compounds. Specimens with x = 0.01 and x = 0.93 sintered at 630 °C exhibited the following microwave dielectric properties: εr = 12.4 and 9.8, high Q×f = 57,000 and 21,000 GHz, and τf = –15 and −24 ppm/°C, respectively. This suggests that the (Mn0.99Mg0.01)V2O6 ceramic is a potential material for ULTCC applications.
