COLOSSAL PIEZOELECTRIC RESPONSE IN SOL-GEL DERIVED BARIUM CALCIUM ZIRCONIUM TITANATE CERAMICS

摘要

Abstract COLOSSAL PIEZOELECTRIC RESPONSE IN SOL-GEL DERIVED BARIUM CALCIUM ZIRCONIUM TITANATE CERAMICS In the present invention there is provided a process of preparing lead free Barium Calcium Zinc Tantalate (BCZT) ceramics by optimizing processing parameter to increase piezoelectric properties. The said optimized processing parameters are further applied to synthesize doped lead free BCZT ceramics which exhibits excellent piezoelectric properties.
