The BaTiO3 particles were coated by La2O3 and SiO2 using a double-coating approach.
BaTiO3@La2O3@SiO2 particles with a multi-level core-shell structure were obtained.
Fine-grained BaTiO3@La2O3@SiO2 ceramics met the X8R specification were prepared.
The prepared ceramics are to be utilized in multi-layer energy storage capacitors.
