The effect of Zr content on electrical properties of Ba(Ti 1-xZrx)O3 ceramics
The effect of Zr content on the crystal structure and electrical properties of barium zirconate titanate (Ba(Zr,Ti)O3) was studied by X-ray diffraction and dielectric, ferroelectric and impedance spectroscopy. An increase of Zr content into BaTiO3 leads to a reduction in its c-parameter and an incre...
