| PIN-PMN-PT (Pb(In1/2Nb1/2)O3-Pb(Mg1/3Nb2/3)O3- PbTiO3) single crystals with 26%-59% PIN were successfully grown by Bridgman technique. Elastic, dielectric and piezoelectric properties of ternary PIN-PMN-PT crystals were studied in comparison with PMN-PT (Pb(Mg1/3Nb2/3)O3 - PbTiO3) crystals. It was demonstrated that PIN-PMN-PT crystals possess as excellent piezoelectric properties as PMN-PT crystals, but can be operated at elevated temperature and AC electric field without the depoling issue. TRT of PIN-PMN-PT crystals with 26%-36% PIN were roughly in the range of 115 -135„aC, 30-40„aC higher than that of PMN-PT crystals; meanwhile, EC were on the order of 4.5-5.6kV/cm, two to three times higher than that of PMN-PT crystals. A full set of measured or derived elastic, piezoelectric and dielectric properties of PIN-PMN-PT crystals are present in this paper. |
