Abstract
Highly optically transparent ceramics of (1−x) Pb ( Mg 1/3 Nb 2/3) O 3–x Pb ( Zr 0.53, Ti 0.47) O 3 ( 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.
