The modified polymer‐network gel route has been developed to prepare a multilayer core –shell structure ofBaTiO 3 ‐ based dielectric ceramics. The core of particle was BaTiO 3 , whereas 0.7 BaTiO 3 –0.3 Bi ( Zn 1/2 Ti 1/2 ) O 3 (0.7 BT –0.3 BZT ) and Nb oxides were coated as the multilayer shell compositions, which were confirmed by energy dispersive spectroscopy testing. The dielectric properties of BaTiO 3 ‐based samples with multilayer core–shell structure were found to meet the X9R specification. The dielectric constant was 1190 and the dielectric loss was 1.3% at room temperature.
