To improve the temperature stability of Ba(Fe0.5Nb0.5)O3 (abbreviated as BFN) ceramics, the core-shell structure of Ba(Fe0.5Nb0.5)O3@SiO2 (abbreviated as BFN@SiO2) particles were successfully prepared by aqueous chemical coating approach. The effect of insulating SiO2 layer on the microstructures and dielectric properties of BFN ceramics was investigated. TEM shows that the thin SiO2 layers (about...
