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