| 摘 要： | 采用复合添加BaCuO_2-CuO(以下简称BCC)、ZnO-B_2O_3-SiO_2(以下简称ZBS)等烧结助剂的方法,研究了Ba_4(Nd_(0.85)Bi_(0.15))_(28/3)Ti_(18)O_(54)陶瓷(以下简称BNT)低温烧结的烧结特性和微波介电性能。结果表明:复合添加(均为质量分数)2.5％BaCuO_2-CuO和5％ZnO-B_2O_3-SiO_2后可以在1050℃烧结成致密瓷,气孔率为5.73％,在5.6 GHz,相对个电常数ε_r为64.25,Q·f值为2026 GHz,频率温度系数τ_f为+26.4×10~(-6)℃~(-1),可望实现与Cu电极浆料低温共烧。

| Abstract: | The effects of liquid additives BCC (BaCuO_2-CuO) and ZBS glass (ZnO-B_2O_3-SiO_2) on the sinterability and
microwave dielectric properties of Ba_4(Nd_(0.85)Bi_(0.15))_(28/3)Ti_(18)O_(54) ceramics were investigated. A kind of low temperature co - fired
ceramic was obtained by sintered at 1050℃ with the addition of 2.5 wt% BaCuO_2-CuO and 5wt%ZnO-B_2O_3-SiO_2, showed
good microwave dielectric characteristics: ε_r=64.25, Q·f=2026 GHz(5.6 GHz),τ_f=+26.4×10~(-6)℃~(-1), and this dielectric
ceramics is cofirable with Cu-electrode. |
