Influences of cobalt dopant on the phases, microstructures and dielectric properties of PZT ceramics

The effects of cobalt dopant on the properties of PZT ceramics with the formula of Pb(Zr 0.52 Ti 0.48 ) 1-x Co x O 3 (where x = 0, 0. 002, 0. 005, 0. 01, 0. 015. 0. 02, 0. 025 and 0. 03) were studied. The cobalt doped PZT ceramics were produced using a conventional mixed oxides route. Phase structu...
