摘要：
The liquid phase screening method was used to search for sintering aids for 0.88(Bi0.4K0.2Na0.2Ba0.2)TiO3-0.12Sr(Mg1/3Nb2/3)O-3 ceramics. The efficiency of the method was tested by studying the effect of three selected oxides on the densification and properties of the ceramics. The results showed that all three selected sintering aids can improve the sintering ability and energy storage performance. The sample with 1.5 mol% SiO2 exhibited a recoverable energy storage density and storage efficiency of 2.61 J/cm(3) and 77.4% at an electric field of 270 kV/cm, indicating its promising applications in the low-to-moderate fields.
