Improvement in piezoelectric strain of annealed Ba(Zr0.07Ti 0.93)O3 based ceramics
In the present work, effects of annealing time on strain behavior, densification, and microstructure of 2 wt. % B 2 O 3 doped Ba(Zr 0.07 Ti 0.93 )O 3 ceramics were investigated. The ceramics were initially sintered at 1150 to 1275°C for 2 h. After sintering, the densest ceramics (1250°C ceramics) we...
