Abstract: The effects of liquid additives (CuO, V2O5, LiF, PbO, H3BO3, Bi2O3) on the sinterability and dielectric properties of bismuth-based ceramics were
investigated. The sintering temperature of all these materials are lower than 900℃. Nb2O5 ZnO-Bi2O3 ceramics with ε r=150--170,
tanδ=0.002--0.008(100Mhz) and Δ C/C≤±5%(1Mhz) were obtained.

Key words: liquid additives, low-firing, dielectric ceramics
