Abstract

In this paper, the effects of O2 and N2 sintering atmospheres on the physical phase and microstructure of BSIT ceramics were investigated by using In3+-doped BST ceramics as the research object. And then the dielectric properties of the ceramics in the frequency range of 20Hz-300000 Hz were investigated by constructing ceramic capacitors. The results show that the ceramic sintered in N2 atmosphere has a denser morphology and a higher dielectric constant of 862 compared with the ceramic sintered in O2 atmosphere, and the dielectric loss is reduced by about 39% in the high frequency stage


Keywords: In2Se3, BST-based ceramics, Sintering atmosphere, Dielectric properties
