摘要

A method of making a single crystal of lead magnesium niobate-lead titanate (PMN-PT). The method includes providing a flat-bottomed iridium crucible containing PMN-PT starting material, and placing the crucible into a vertical Bridgman furnace having at least two temperature zones, which is subsequentially pressured with an inert gas. The crucible then descends into the temperature zones of the vertical Bridgman furnace. The temperature zones of the vertical Bridgman furnace include a first temperature zone having a temperature higher than a melting temperature of the PMN-PT material and a second temperature zone having a temperature less than the melting temperature of the PMN-PT material. The single crystals of the PMN-PT prepared using the above-described method exhibits a [110] crystal orientation and may be used in electroacoustic transducers. The electroacoustic transducers are useful in devices that detect or generate acoustic waves.
