• The CZ addition helps BNBT6 obtain the lower porosity and uniform surface.
• The introduction of CZ lowers TF–R and enhances relaxor-ferroelectric of BNBT6.
• The energy storage of BNBT6 is enhanced by CZ addition.
The 0.94Bi0.5Na0.5TiO3–0.06BaTiO3(BNBT6) introduced by CaZrO3(CZ) lead-free ferroelectric ceramics are successfully fabricated by conventional solid state reaction. The influence of CZ substitution on the phase transition, microstructure, dielectric, ferroelectric, and energy storage properties of (1 − x)BNBT6-xCZ ceramics are systematically investigated. The energy-storage density 0.7 J/cm3 under the electric field 70 kV/cm is obtained in the 0.97BNBT6-0.03CZ. In addition, its energy-storage property exhibits thermal stability at the temperature range of 30–130 °C.
