A new type (1−x)(K0.485Na0.485Li0.03)NbO3–xPb(Zr0.53Ti0.47)O3 piezoelectric ceramics was fabricated by conventional ceramics sintering technique. Their microstructure and electrical properties of the ceramics were also studied. X-ray diffraction and scanning electron microscopy patterns indicate that all ceramics samples exhibit a pure perovskite and highly dense structure, and the coexistence of the tetragonal and orthorhombic phases is formed; The ceramic with x=0.75 exhibits the following excellent properties: d33=363 pC/N, kp=63%, Qm=142, ɛr=1590, tan δ=1.70%, Pr=28.6 μC/cm2, Ec=0.89 kV/mm, Tc=295°C. These results indicate that the ceramic is a promising candidate for piezoelectric ceramics in practical applications.
