摘要：
Lithium tantalate, LiTaO3 (LT), single crystal growth by the vertical Bridgman (VB) technique is attempt for the first time. In the present VB-LT technique, pure platinum crucibles are used in a furnace with a graphite heater and an argon atmosphere. One-hundred percent solidified crack-free VB-LT crystals are successfully grown by composing the initial melts with exactly congruent compositions. The fundamental technical issues for VB-LT growth are also clarified.
