International Journal of Minerals,Metallurgy and Materials 2000年第2期14卷 115-117页

作者： Zhen Ji Zhhong Xiao xuqing liu Zhaozeng Ma Zongsen Yu(Material Science and Engineering School, University of Science and Technology Bejing, Beijing 100083, China) Material Science and Engineering School University of Science and Technology Beijing Beijing 100083 China

The effects of different firing temperatures on the stability of perovskite phase, grain size, and dielectric properties were investigated by XRD, TEM, SEM and dielectric measurements. The dielectric ceramics of Pb(Mg1/3Nb2/3)O3-PbTiO3-BaTiO3 system were obtained by chemical coprecipitation in water. The ceramics have higher dielectric constant (7003-9714), lower firing temperature(950-1150℃), quite uniform microstructure with grain size less than 2.5 mp, and lower temperature coefficients of capacitance. As a re-sult, it was confirmed that the simple and low cost chemical route used namely coprecipitation in water is a desired method for preparinghigh property dielectfic materials applicable to multilayer capacitors.
