Dielectric and piezoelectric properties of Ba(Zr xTi1-x)O3 lead-free ceramics

Lead-free ceramics Ba(Zr xTi1-x)O3 (x = 0.02-0.2) were prepared using a solid-state reaction technique. The structural and electrical properties were systemically investigated. Crystalline structures and microstructures were analyzed by X-ray diffraction and scanning electron microscope (SEM) at room temperature. All the samples possess pure perovskite structure. A small amount of Zr content has great effect on the microstructure of Ba(Zr xTi1-x)O3 ceramics. The homogeneous microstructure with grain size about 30µm is obtained for the sample at x = 0.05. The phase transitions merge together i...
