摘要

Sintering temperature of the Ba(Zn_(1/3)Ta_(2/3_)O_3 (BZT) ceramic is about 1550℃ and it decreased to 950℃ when B_2O_3 was added. The BaB_4O_7 second phase whose melting temperature is 889℃ was found in the B_2O_3 added BZT ceramics. The BaB_4O_7 second phase assisted the sintering of the BZT ceramics at 950℃. However, the B_2O_3 added BZT ceramic was not sintered below 950℃ and the microwave dielecric properties were not satisfactory. On the other hand, when the B_2O_3 and the CuO were added, the BZT ceramic was sintered even at 870℃. The BaCu(B_2O_5) phase which was found in the CuO and B_2O_3 added BZT ceramics, existed as the liquid phase during the sintering and helped the densification of the BZT ceramics at temperatures lower than 950℃. Good microwave dielectric properties of Q x f = 11,000 GHz, ε_r = 26 and τ_f = 0.0 ppm/℃ were obtained from the BZT + 5.0 mol% B_2O_3 + 10.0 mol% CuO ceramic sintered at 870℃ for 2h.
