Highly optically transparent ceramics of (1− x) Pb( Mg1/3 Nb2/3) O3- x Pb( Zr0.53, Ti0.47) O3 ( PMN- PZT) were fabricated by a two-stage sintering method without La-modification. The ceramics exhibited high optical transparency (64% at 1500 nm) for visible and near infrared wavelength. The ferroelectric domain and microstructure of PMN- PZT transparent ceramics prepared were also investigated. Fully dense microstructure was observed in all PMN- PZT transparent ceramic samples. Higher PMN containing compositions exhibited pyrochlore phase and relatively lower transparency for near infrared wavelengths. Fine and irregular fingerprint ferroelectric domains were observed in all PMN- PZT compositions except in the PMN- PZT 67/33 composition that had dense microstructure and pure perovskite phase. This PMN- PZT 67/33 composition exhibited the lowest transparency (40% at 1500 nm) with large-scale macrodomain structure. [ABSTRACT FROM AUTHOR] |
