Vanadium doped Bi4Ti3O12powder was prepared by a co-precipitation method and its phase evolution process, microstructure and sintering behavior were investigated. The results indicate that Bi4Ti3O12 crystalline phase with grain sizes of less than 100nm can be obtained by calcination of the precursor at 550℃, which is 250℃ lower than that of traditional solid reaction. The powder possesses a good sintering activity and the bulk density of sintered samples can reach 96% of theoretical value when sintering at 900℃ for 1h. In comparison to the material prepared by solid reaction, the sample made from the co-precipitation powder also has lower dielectric loss.
