摘要
In this work, lead-free piezoelectric ceramics 0.65Bi(1.05)Fe(1-x)Ga(x)O(3)-0.35BaTiO(3), where x=0, 0.01, 0.02, 0.025, and 0.03 abbreviated as BFG-BT have been synthesized by a conventional solid-state reaction followed by air quenching process. The effects of Ga on crystal structure, microstructure and electric properties of the ceramics have been investigated. X-ray diffraction analysis showed that Ga addition into BF-BT ceramics caused no significant change in crystal structure. However, improvements in ferroelectric, dielectric and piezoelectric properties were obtained at the optimum composition of Ga addition in BF-BT ceramics. A static piezoelectric constant of d(33)=145 pC/N with high Curie temperature T-C=452 degrees C were obtained at 2mol%Ga modified BF-BT ceramics.
