Zusammenfassung:The addition of ... to ... 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 ... during the sintering. For the specimens sintered at 800...C, the grain size was considerably increased when the ... content exceeded 1.0 mol%. The Qxf value was increased by the ... addition due to the increased density and grain size. In particular, a high Qxf value of 73 800 GHz with ... and ... values of 9.94 and --28.8 ppm/...C, respectively, was obtained for the specimen containing 3.0 mol% ... sintered at 800...C for 2h.
