Elastic, piezoelectric, and dielectric properties of 0.71Pb(Mg 1/3Nb2/3)O3-0.29PbTiO3 crystals obtained by solid-state crystal growth

Journal Article


Abstract


  • Single crystals with the composition of 0.71Pb(Mg1/3Nb 2/3)O3-0.29PbTiO3 (PMNT29) were grown using the solid-state crystal growth (SSCG) method. Compared with the conventional Bridgman grown crystals, the SSCG PMNT29 crystals were found to possess comparable piezoelectric, dielectric, and electromechanical properties (d 33∼1500 pC/N, εT33/ε0 ∼5400 and k33∼90%), with the same Curie temperature (T C) and ferroelectric phase transformation temperature (T R-T). The full set of elastic, piezoelectric, and dielectric material constants were determined by the resonance method for the SSCG grown PMNT29 crystals according to IEEE standards and compared with Bridgman grown crystals. The dielectric temperature behavior and the strain field characteristics were investigated, demonstrating excellent performance over the temperature range from room temperature to 95°C. Strain behavior at high electric fields was found to be different from Bridgman growth crystals and believed to be attributed to different domain structures. © 2007 The American Ceramic Society.
