The Effect of Different Doping Methods of Sintering Aids on the Barium Titanate Based X7R Ceramics

摘要

The barium titanate based X7R ceramics, which are doped with rare earth oxide, Nb_2O_5, Co_3O_4 and ZnO-B_2O_, could be sintered at a rather low temperature to satisfy the X7R requirements with good permittivity and dielectric loss. In this paper, different doping methods of sintering aids have been used to prepare X7R BaTiO_3 ceramics. Samples were sintered at a low temperature and the relationship of doping methods and sintering properties has been concluded.
