The sintering behavior of CeO2-doped strontium barium niobate ceramics

In this study, the isothermal sintering behaviors of pure and CeO2-doped Sr0.5Ba0.5Nb2O6 ceramics were evaluated. It was found that the cerium dopant would increase the sintering temperature and the activation energy of the SBN ceramics sintered in air. The defects for the charge compensation were studied and discussed. It is suggested that the excessive oxygen ion occupying the O(4) site be the defect for charge compensation.
