在了解PMN-PT体系的特性和PMNT晶体的热稳定性的基础上，采用Brid-man技术生长PMNT单晶。与传统方法相比，该技术在控制自发成核、寄生生长、晶体尺寸和完好性等方面具有一定的优势。为了抑制坩埚的漏电，改善成分的均匀性，提高压电性能，对原料和晶体生长工艺进行了改进。用该方法生长的PMNT晶体尺寸较大，具有优良的压电性能。(C)2001爱思唯尔科学有限公司。保留所有权利。
The Brid-man technique has been used to grow PMNT single crystals based on the understanding of the features of PMN-PT system and the thermal stability of PMNT crystals. The technique has some advantages for the control of spontaneous nucleation, parasitic growth, crystal size and perfection compared to conventional methods. In order to suppress the leaking of crucibles, improve the compositional uniformity and enhance the piezoelectric performance, some modifications were adopted in starting materials and crystal growth procedure. The PMNT crystals grown using this technique were large in size and excellent in piezoelectric properties. (C) 2001 Elsevier Science Ltd. All rights reserved.
