Abstract

The addition of Li₂CO₃ to Sr₂V ₂O₇ ceramics decreased their sintering temperature and time. A dense microstructure was developed for the specimens sintered at 750°-850°C due to the melting of Li₂CO₃ during the sintering. For the specimens sintered at 800°C, the grain size was considerably increased when the Li₂CO₃ content exceeded 1.0 mol%. The Q × f value was increased by the Li₂CO ₃ addition due to the increased density and grain size. In particular, a high Q × f value of 73 800 GHz with ε_r and τ_f values of 9.94 and -28.8 ppm/°C, respectively, was obtained for the specimen containing 3.0 mol% Li₂CO₃ sintered at 800°C for 2h.
