Influence of Ca substitution on microstructure and electrical properties of Ba(Zr,Ti)O 3 ceramics

In the present work, lead-free (Ba 1-x Ca x )(Zr 0.04Ti 0.96)O 3 (x=0.00-0.09) ceramics were fabricated via a solid-state reaction method. The microstructure and electrical properties of the ceramics were investigated. The microstructure of the BCZT ceramics showed a core shell structure at composit...
