摘要：
(Bi1.5Zn0.5) (Zn0.5Nb1.5)O7(BZN) main phase are prepared by solid phase reaction using Bi2O3, ZnO and Nb2O5 as raw material. B2O3 was introduced by liquid coating technology and solid phase mix method in the BZN ceramic specimen to reduce its sintering temperature. The effects of B2O3 doping on the sintering and dielectric properties of BZN were studied. The results show that liquid coating with B2O3 could decrease the sintering temperature of BZN ceramics from 1100°C to 900°C. The BZN ceramic composite could be sintered well at 900°C for 3 h when 0.9 mol/L H3BO3 was added and showed good dielectric properties of Εr=150, Q×f=228, τf=-362 ppm/°C.
