• Pure perovskite (Ba0.85Ca0.15)(Zr0.1Ti0.9)O3 (BCZT) precursor powder with rather uniform micro-morphology in dozens nanometer was synthesized by the hydrothermal method, which presents high sintering active for preparing the BCZT ceramics at low sintering temperatures. Via adjusting sintering conditions, rather pure perovskite structure BCZT ceramics are obtained accompanied by high densification, gradually change of microstructure morphology and mainly pseudo-cubic structure. Furthermore, versatile dielectric, ferroelectric, piezoelectric and pyroelectric properties can be tailored in the BCZT ceramics prepared via the hydrothermal method. Although slight dielectric frequency dispersion is observed, the hydrothermal method synthesized BCZT ceramics approaches to normal ferroelectrics. Excellent ferroelectricity, energy-storage performance and pyroelectricity can be achieved in the BCZT ceramics via tailoring sintering conditions, which provide versatile potential applications in electronic devices. •Lead-free (Ba0.85Ca0.15)(Zr0.1Ti0.9)O3 (BCZT) piezoelectric ceramics were prepared successfully via the hydrothermal method sintered at rather low temperatures.•The hydrothermal method synthesized BCZT precursor powder exhibits pure perovskite structure with rather uniform micro-morphology in dozens nanometer and high sintering active.•The BCZT ceramics present high density and versatile electrical properties depending on sintering conditions.•The BCZT ceramics exhibit improved energy-storage performance and pyroelectricity, which provides versatile potential applications in electronic devices.
