BCZT Ceramics Prepared from Activated Powders

Ultra-fine BayCa1-y(ZrxTi1-x)O3 powders, with y = 0.89 and x = 0.10, has been synthesized by solid state reaction route from commercial BaCO3, CaCO3, TiO2 and ZrO2 powders using the high-energy ball milling technique in air at room temperature. Dense BCZT ceramics were prepared by varying the sintering conditions from green pellets obtained by uniaxial pressing of powders calcined at 800C. The results of dielectric and ferroelectric properties show that the high-energy ball milling process is a practical and promising way to prepare BCZT ceramics
