Abstract

Abstract: 0.24Pb(In1/2 Nb1/2 )O3 ‐0.42Pb(Mg1/3 Nb2/3 )O3 ‐0.34PbTiO3 transparent ceramics were fabricated by a conventional sintering technique. Through optimization of sintering conditions of calcination and sintering temperatures and time, the obtained ceramics showed high optical transmittance of 53% and 71% at light wavelengths of 1300 and 2000 nm, respectively. The ceramics showed a rhombohedral to tetragonal phase transition at ~120°C and a tetragonal to cubic phase transition at 222°C. These transition temperatures were higher than those of 0.67Pb(Mg1/3 Nb2/3 )‐0.33PbTiO3 ceramics. In addition, the ceramics had a ferroelectric hysteresis loop, a large piezoelectric constant d 33 of 407 pC/N, and a planar electromechanical coupling factor k p of 52%. These results suggest that the transparent ceramics may be used as a temperature‐stable, linear electro‐optic material.
