  • Description: A double core-shell structural nanoparticles Ba 0.8 Sr 0.2 Zr 0.1 Ti 0.9 O 3 MgO-Al 2 O 3 @ZnO-B 2 O 3 -SiO 2 (BSZT@MgO-Al 2 O 3 @ZBSO) preparative technique was applied to produce BSZT@MgAl 2 O 4 @ZBSO ceramics with excellent energy storage performance. The BSZT@MgO-Al 2 O 3 @ZBSO particles had a diameter of about 280 nm, high uniformity and high dispersity fabricated using a double-coating approach to simultaneously improve BDS and densification of the ceramics. The MgO-Al 2 O 3 and ZBSO layers in the BSZT@MgO-Al 2 O 3 @ZBSO particles averaged about 8 and 13 nm, respectively, in thickness. MgO-Al 2 O 3 in the intermediate layer were self-assembly to MgAl 2 O 4 spinel phase during sintering at 1150 °C for 2 h. We obtained dense, fine-grained relaxation ferroelectric BSZT@MgAl 2 O 4 @ZBSO ceramics (grain size ≤ 300 nm). When the Mg/Al ratio is 4:2, the ceramic has a maximum energy storage density of 0.91 J/cm 3 under a maximum polarization field of 28.08 kV/mm
