摘要：

The structure and properties of Mg-doped SrBi4Ti4O15(SBT) were dicussed. Mg substitution into SBT had two possibilities states with the dopant amount variety. Mg cation substituted mostly into Sr2+ and the amount proportion was 68.11% Mg ion will substitute into Ti ion site in perovskite layer when the doping amount increases. Polarization increases sharply when x=0.1 and then decreases becauses of the domain pinning. The Curie temperature of Mg-doped SBT is about 300 degrees C and there is a broad diffuse phase transition near T-c with a flat peak near the T-a of SBT.
