摘要： A method of making a single crystals of lead magnesium niobate-lead titanate (PMN-PT). The method includes providing a crucible containing PMN-PT starting material, and placing the crucible into a furnace having at least two temperature zones, which is subsequently pressured with an inert gas. The crucible then descends into the temperature zones of the vertical. The temperature zones of the 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 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.
