Zusammenfassung:... ceramics were synthesized and their microwave dielectric properties were investigated. The ... second phase was formed at approximately 400...C, while the ... and ... phases started to form at 600...C. The amount of the ... and ... second phases decreased as the firing temperature exceeded 650...C. A homogeneous ... phase was obtained for the specimen fired at 850...C. For the specimens sintered at 900...C for more than 5 h, high-density ... ceramics were obtained. In particular, the ... ceramics sintered at 900...C for 8 h exhibited the good microwave dielectric properties of ...=14.9, Q x f=36 101 GHz and ...=9.42 pp/...C.
