Abstract
The formation process and microwave dielectric properties of the Mg 2V2O7 ceramics were investigated. The MgV 2O6 phase that was formed at around 450°C interacted with remnant MgO above 590°C to form a homogeneous monoclinic Mg 2V2O7 phase. Finally, this monoclinic Mg 2V2O7 phase was changed to a triclinic Mg 2V2O7 phase for the specimen fired at 800°C. Sintering at 950°C for more than 5 h produced high-density triclinic Mg2V2O7 ceramics. In particular, the Mg2V2O7 ceramics sintered at 950°C for 10 h exhibited the good microwave dielectric properties of εr=10.5, Q × f=58 275 GHz, and τf=-26.9 ppm/°C.
