Effects BNT compound incorporated on structure and electrical properties of PZT ceramic
Ferroelectric ceramics with formula Pb(Zr0.52Ti0.48)O3/x(Bi0.5Na0.5)TiO3(when x = 0, 0.1, 0.5, 1.0 and 3.0 wt%) were prepared by a solid-state mixed-oxide method and sintered at the temperature between 1050 and 1200 °C for 2 h to obtain dense ceramics. It was found that the optimum sintering tempera...
