Perovskite Pb(Zn 1/3 Nb 2/3 )O 3 (PZN) was obtained by first fabricating pyrochlore PZN ceramics and then converting pyrochlore to perovskite using HIP. PZN ceramics containing as much perovskite as 96% were fabricated under 200 MPa at 1150°C for 1 h. The electromechanical coupling factors and the piezoelectric constants were lower than expected, probably due to the low relative density of the specimen measured.
