| 摘 要： | 以EDTA为络合剂,EG为酯化剂,得到多孔的BaNd2Ti4O12树脂前驱体,在950～1 000℃内预烧,可直接合成BaNd2Ti4O12而不出现中间相。聚合物前驱体法制备BaNd2Ti4O12在1 140～1 180℃的内可以烧结得到致密的陶瓷,较传统固相法烧结温度低200℃左右。1 140℃烧结的样品介电性能良好,εr为87.6,Qf为7 692。

| Abstract: | The ternary BaNd2Ti4O12 ceramics were synthesized by the polymeric precursor method and its conditions were studied.The BaNd2Ti4O12 ceramics with excellent microwave properties were prepared by using EDTA as a chelating agent.When the ceramics powders calcined at 950～1 000 ℃,the pure phase can be got.The BaN d2Ti4O12 ceramics made by the polymeric precursor method has lower sintering temperature than those made by the conditional solid-state method,that is between1 140～1 180 ℃.When calculated at 95 0 ℃ and sintered at 1 140 ℃ the ceramics has excellent dilectric properties with εr =87.6,Qf=7 692。 |
