Abstract
A ternary single crystal relaxor piezoelectric grown from a novel melt using the Vertical Bridgeman method. The ternary single crystals are characterized by a Curie temperature, T, of at least 150° C. and a rhombohedral to tetragonal phase transition temperature, T, of at least about 110° C. The ternary crystals further exhibit a piezoelectric coefficient, d, in the range of at least about 1200-2000 pC/N.
