To research effect of raw materials TiO2 with the phase structures on the crystal structure, microstructure and electrical properties of lead-free (Ba0.85Ca0.15)(Ti0.90Zr0.10)O-3 (BCZT) ceramics, BCZT ceramics using either anatase or rutile as Ti source were synthesized by solid-state reaction. Titanium dioxide (TiO2) with anatase/rutile phase structures had interesting influence on the crystal structure, microstructure and the sintering temperature by the X-ray diffraction and SEM, which also played an important role in improved electrical properties. The BCZT ceramics with rutile titanium dioxide demonstrated optimal piezoelectric and dielectric properties: d(33) = 590 pC/N, k(p) = 0.46, epsilon(r) = 2810, tan delta = 0.014 and T-c = 91 degrees C, which was obviously superior to BCZT ceramics with anatase titanium dioxide.
