      • Abstract
    • (Bi1.975Li0.025)(Zn2/3Nb4/3-xVx)O7(BLZNV) ceramics were prepared by solid phase reaction.The effect of(Li,V) dope on sintering temperature,phase structure and dielectric properties of Bi2(Zn1/3Nb2/3)2O7(BZN) ceramics was investigated.The results show that(Li,V) doping could decrease the sintering temperature of the BZN ceramic remarkably from 1 000 ℃ to 860 ℃.The ceramics had single monoclinal pyrochlore phase when x≤005.Relaxation appeared during dielectric loss.When x were 0.005,0.01,0.02 and 0.05,the peak temperatures of(Li,V) doped samples were 125,120,112 and 100 ℃,respectively.A shift of the relaxation peak to low temperature was caused by activation energy decreasing.
