## Description

- description: We report a non-Pb piezoelectric ceramic system Ba(Ti0.8Zr0.2)O3−(Ba0.7Ca0.3)TiO3
    which shows a surprisingly high piezoelectric coefficient of d33∼620  pC/N at
    optimal composition. Its phase diagram shows a morphortropic phase boundary (MPB)
    starting from a tricritical triple point of a cubic paraelectric phase (C), ferroelectric
    rhombohedral (R), and tetragonal (T) phases. The high piezoelectricity of the
    MPB compositions stems from the composition proximity of the MPB to the tricritical
    triple point, which leads to a nearly vanishing polarization anisotropy and thus
    facilitates polarization rotation between ⟨001⟩T and ⟨111⟩R states. We predict
    that the single-crystal form of the MPB composition of the present system may
    reach a giant d33=1500–2000  pC/N. Our work may provide a new recipe for designing
    highly piezoelectric materials (both Pb-free and Pb-containing) by searching MPBs
    starting from a TCP.
