用共振-反共振方法研究了铁电bi4ti3o12 （BiT）单晶的压电特性。在0.9 MPa的高氧压力下，通过顶种子溶液生长获得了大而高质量的BiT单晶。首次测定了BiT单晶（11）、（12）、（13）和（26）模式下的弹性常数和压电常数。结果表明，BiT具有79 pC/N的大d26常数和40%的大k26因子，表明BiT是一种很有前途的用于剪切型压电器件的铁电材料。
Piezoelectric properties of ferroelectric Bi 4 Ti 3 O 12 (BiT) single crystals have been investigated by a resonance–antiresonance method. Large and high-quality single crystals of BiT were obtained via top-seeded solution growth under a high oxygen pressure of 0.9 MPa. The elastic and piezoelectric constants in the (11),(12),(13), and (26) modes for BiT single crystals have been determined for the first time. It is shown that BiT has a large d 26 constant of 79 pC/N and a large k 26 factor of 40%, indicating that BiT is a promising ferroelectric material for application to shear-mode piezoelectric devices.
